Wow, there are a lot of Dalek stories here. New Who really ruined the Daleks.
Really? Some of them were pretty nice episodes, why were they bad for you? (Just curious, always wish people would say why, it makes it more interesting and sometimes make you think).
As for me. Only started watching the Doctor Who series last year, first started watching the tenth doctor, and thought he was awesome. So went back and watched the 9th Doctor, he was cool, not too bad at all. Smith was a bit... goofy I guess? He did grow on me at the end of the series, but it was hard to take him seriously compared to the other doctors. Because of about four, or five friends of mine I started getting hooked on it.
I have only just started going back in time, watching the older Doctors (Getting off Itune, each of the first and last episodes for all the doctors, well except the last three since I already seen them). I am really liking the 3rd and 4th Doctor, I like the 3rd's outfit strangely enough, and 4th's kinda funny, and weird looking (Nothing wrong with that). At first I couldn't watch the classic series, because of the corny backgrounds, fake monsters etc, but I am getting kinda used to it, that I can watch it enough. 7th Doctor interests me for some reason as well, the name sounds familiar for some reason (And he looks like one of the recurring characters on Modern Family).
Planning to watch some of the first and second ones (Really a shame the Tenth Planet has the last one missing, seriously what kind of idiot would erase that. Personally I think it's gone forever, lost for all eternity in time. Just because they are offering a life sized Dalek, and a fan or not, can you imagine getting one of those? It's a collectors one, and I bet for the non fans, you could sell it for tons). It is weird watching the first, second and third doctors considering the actors have passed, but at the same time interesting to see where it all started.
Edit: I agree about the Silthereens, when I first watched that episode, it was hard to take seriously, especially the aliens being bad (Might be because I saw a review of it beforehand, and they were talking about how they had a baby face with big eyes... Now that's all I see). Plus their movements seem kinda fake at times.
