I always hated KND: Kids Next Door... not only it was kind of silly and the so no original idea of the kids thinking of the adults as villains, the design was overall bad, like really bad, almost like every children product's mascot bad and we already have enough of that on the tv adds. The other ones, maybe not hated but disliked was every Klasky/Csupo animation.... they were all booooring.
Proud Family. The utter -nadir- of what Disney's pushed on us. Reasons? -Characters are cardboard cutouts and unlikeable(Well-meaning and idiot dad, mom with control issues, grandmother with years of wisdom, infants who can get away with murder, protagonist who follows the path of every not quite teen protagonist in every family sitcom...) I don't give a **** about any of them! -The big anti-piracy episode was a very poor Matrix riff, and ended nonsensically without addressing any of the issues involved -One of the bullies gets better, stops bullying, becomes a better person. Until the end of the episode where she's peer pressured back to being a bully
Most stuff from the 80's/very early 90's is pretty terrible if you actually go back and watch the old TMNT it is just horrid same goes for the Old Mario and Zelda cartoon even G1 Transformers (though I'll probably catch some slack about that one). But ya most stuff back then is really bad. As for bad Anime I was never a fan of Evangelion I thought the primes was great and I loved the Eva's themselves because they weren't the usual giant robot fighter they moved fluidly. They could flip and dive and take cover and all that jazz. But a lot of the characters were terrible and annoying.
That and I'm never a fan of anime's that end with mind fucks, which Evangelion does, always a pain in the ass. I love The Big O but hate the ending because it's a mind fuck and worse than that as well but I won't say more because I don't want to ruin the ending for anyone who hasn't seen it. But honestly I would suggest watching The Big O it was a great series I just didn't like the ending. Everything up to the ending was awesome and who knows I'm sure there are some people out there that like the ending.
