I'm not actually a rabid fangirl as you seem to think. I prefer other books, such as Inheritance and the Warriors series by Erin Hunter. But my preferences in books are irrelevant.
I don't think Edward nor Bella are sues. Bella is extremely whiny and annoying by my standards, and Edward is possessive, and well, cold and dead. Not hot and sexy by my standards at all, but meh, whatever floats your boat.
Bella calls Edward attractive at least ten times a page. His "gorgeous lips", "Seraphic eyes", and "sweet-smelling breath" are all indicators of his attractiveness, and she uses adjectives such as those every time she describes Edward. Not to mention how, in the first chapter, the author stated that all of the Cullens were "inhumanely beautiful". So that either means that Edward is super hot, or really feminine.
On the topic of Bella, she fits all of the signs of a Mary Sue. Plain, ordinary, but everyone loves her (in the first chapter everyone was obsessing over her moving to Forks, for some reason). Her blood is apparently delicious and "irresistable" - though, again, there's no explanation as to why. When the Cullens first meet her, they put their lives on the line to save her from James, though she's a plain, ordinary, clumsy, unattractive human girl.
The hottest, richest guy in school loves her, though she's ugly, clumsy, plain and ordinary, and states that he would rather die without her by the time the second book comes along (and tries to committ suicide). That is all just so Tragic!Sue-like to me. If Edward was your typical high school hottie, and Bella didn't have "delicious" blood, he wouldn't go near her. Period. The books are filled with poorly-described plotlines that simply are there for convenience. J.K. Rowling always explains the reasoning behind things, such as Priori Incantatem and why Harry beat Voldemort. If SMeyer wrote HP, she wouldn't have explained anything.
Oh, and about the mormon religious values, I believe Religion is mentioned, umm, correct me if I'm wrong, twice. Once, when Carlisle mentions he doesn't believe in God, and again when either Bella or Jacob (forgive my memory) refers to a passage in the Bible to the other to describe the circumstances.
In Breaking Dawn, Stephenie Meyer took all of the characters values, threw them in the garbage, and gave them "anti-abortion", "no-sex-before-marriage", and other conservative values out of the blue when it was obvious that they didn't have those values before.
Super-rich? Possible. Hot? Possible. Immortal? Okay, maybe not. But the thing is, it's not all a totally happy ending if you happen to have read Breaking Dawn. Bella struggles to deal with her desire to drain her own father of his blood, and Leah is still left without a partner.
Yes, but she still had a fairly easy struggle with her blood urges compared to what Edward described in Twilight. Edward actually had struggles, and sometimes he failed to restrain them, while Bella just went along happily in her "small but perfect piece of her forever". The author's style of writing is to MAKE you think that there will be conflict, but in the end nothing happens. No deaths, no injuries, and EVERYONE has to live happily ever after. So what if Leah didn't have a partner? That's what's wrong with these books! They try to make girls think that they have to have a man to rely on. You can still live happily ever after, even without a partner.
Look at Jacob's situation. Wouldn't it have been better just to leave him along, instead of pairing him up with an infant? It doesn't make any sense! The whole "six years and Renesmee will be fully grown" thing screams "last minute edition to give Jacob more closure". Stephenie Meyer tried to pair up every character, which is what fans thought J.K. Rowling would do, and she paired up Harry and Ginny, Ron and Hermione, and that was it. For everyone else, they ended up with different (mostly unknown) characters, which is how real life works.
Edward is not purely good. He has killed humans in the past, and desires to kill those drunk men when they want to rape Bella.
To protect Bella, however, which was a noble purpose. About him killing humans in the past, he has stated that he regretted it. Stephenie Meyer probably added that little tidbit because she realised how harmless and pathetic Edward was, and because girls love ex-Bad Guys (see every Anime series in the universe for more information).
And remember James? He was very attractive. As was his mate Victoria.
The author never actually described their appearance, but she did describe the Volturi as ugly, green, with red pupils and transparent, onion-like skin. If Bella actually described James and Victoria's attractiveness, she would have probably called them ugly, just as she called the rest of the bad guys "ugly".
Despite the setbacks she faces, Bella's love prevails. So I guess you could say she didn't give up. In fact, giving up on what she really wanted and what her heart desired would be going back to lead a normal life. Edward tells her again and again that she should lead a normal life, but Bella refuses. I don't see how that’s her giving in. She fights for what she loves.
Twilight's idea of "giving up" and Harry Potter's idea of "giving up" is completely different. In Twilight, its all complete vanity and selfishness. Bella's love is for herself and her self-interests, and in Harry Potter his love leads him to sacrifice his own life to take down Voldemort. Harry's love was for humanity, and he made the ultimate sacrifice to save it (technically he did make it, since he thought he was going to die). Bella hated humanity, on the other hand, and even gave her's up to be with her husband her eternity. That's the difference between the two.
Books don't have to have messages either. One thing that infuriates me about society is how they think that everything has to teach you something. This isn't wish fulfilment for me because I would not love to be in Bella's position, because giving birth to a vampire baby at age 18 doesn't appeal to me. Neither do cold, dead sparkly men. I just liked reading Twilight because it offered a fresh and new concept of vampires, one that could almost be scientifically possible.
The character Harry Potter himself actually infuriates me as much as Bella because he is a stereotypical "poor, innocent orphan who finds out he's important". But that's just my opinion. I like both books regardless.
The difference is that Harry DOES something. In the beginning, yes, he fits that characterisation, but by the end of the first book, his character FITS that importance, and he risks his life to prevent Voldemort from coming back to life. Bella does absolutely nothing. Edward does absolutely everything for her, and she does nothing to earn the importance that is given to her, except for having good-smelling blood and being Edward's love interest. That's the only reason why Victoria and the Volturi were after her! Because of Edward!
Oh, and for those of you who say that "fiction doesn't have to be realistic", you're right. But I prefer it if it is somewhat believable, especially fantasy. That's my opinion. I'm not saying Twilight is better because it's more believeable. I'm saying I prefer it because it is.
I just don't see how Twilight is any more believeable than Harry Potter. They're basically on the same level in that department. They both take place in our world, so the setting is the same. What's NOT realistic about Twilight is the characters, while Harry Potter has characters with basic, common personalities. Courageous boy who plays the hero, friendly bookworm know-it-all, and shunned "sidekick" from a poor family. In Twilight, there's no such thing as a "poor" family. Everybody can afford anything, no problem! Ticket to Italy? No problem! Stealing a fancy car in Europe somehow? No problem! Driving across the country without worrying about gas? No problem! Driving to a hotel during spring break and getting a room? No problem! Committing arson on a Ballet Studio? No problem!
