I was into pokemon when it was new and only gen 1 was out, but I think those people are stupid.
I mean, I agree with them to some extent. A LOT of the pokemon in 5th gen are stupid, like Vanilluxe and Garbodor and whatnot. But at the same time, Gen 1 had things like Muk. What is that? Please don't say an animal, because it's not. It's just a toxic blob of waste. Garbodor is pretty similar, just based on a different type of waste. Granted, I think Muk is better due to his simplicity, but those 2 aren't that far off from each other, so to say those kinds of things weren't around in Gen 1 is a little overboard.
And things like Hitmonlee? From the first time I saw it until now, I think it looks utterly stupid. It looks like a slab of meat with arms and legs; a walking steak.
The claims of uncreativity in the later generations...Look at ratata. What the capital f is so creative about that? It's a purple mouse. It looks just like a rat. Put it in a random cartoon to someone who doesn't know pokemon, and surely they'd be fooled into thinking it's just a typical rat in cartoon form.
I think these people who think gen 1 is the best are mainly just nostalgic, because they're arguments for why gen 1 is so supremely superior - to the point that gen 1 (and/or 2) is awesome and all the others are horrible rather than simply taking a strong preference to gen 1 over the rest - are just so...Not right....Like I said, arguments about stupid looking pokemon or uncreative pokemon or whatever as a reason to have so much contempt for recent gens while holding such endearment towards the first one or 2 just seem ridiculous, unthoughtful, and way overboard.
Personally, I've gone through the Pokedex before and made a list of all the pokemon I think are pretty neat and would genuinely want to befriend if they were real and what Gen they're from. Here's how many per generation, including individual pokemon in the same evolutionary line if I liked them:
Gen 1: 9
Gen 2: 8
Gen 3: 7
Gen 4: 17
Gen 5: 12
Granted, some of the ones from earlier gens are missing some pokemon that I still have more liking than usual (like Eevee and Starmie) that just didn't seem like real favorites , and some of the ones from later gens have some included that don't really seem as appealing but were included because they seemed alright (like Salamance and Boldore).
Clearly, given how many pokemon there are, I don't find too many of them very desirable. But there's really not a huge gap for each generation (10 more pokemon than the previous generation compared to the ~100 that were added isn't too much). So, as far as not finding pokemon too aesthetically appealing, I can agree with those people a little - though it applies even to earlier generations, not just later ones. But there were just so many 1st gens (as an example) that I found very unappealing - ratata/raticate, weedle, hitmonlee, machoke/machamp, mankey/primeape, tangela...I could go on.
And then to have them deny the awesome pokemon outside of Gen 1/2? Staraptor is my favorite Bird Pokemon. It's hard for me to see how Pidgeot could be considered cooler...And even from 5th gen, pokemon like Carracosta and Haxorus are just awesome.
I can understand if people like Gen 1 and 2 more, even if part of the reason is nostalgia. But I can't help but think people who just worship Gens 1/2 yet incessantly and mercilessly bash and completely disregard 5th gen are idiots, even knowing that it's an opinion. Their reasoning is just downright crap and you can find almost as stupid pokemon in Gen 1 as you can in Gen 5.
