I don't mean English dubs of anime. I am referring to anime that you don't even like the Japanese version of.
Hetalia is one example. I don't find the humour to be in the best taste. I'm not going into a rant; I'll just say that it's the same reason why I hate Family Guy.
Bakugan is also bad. I just thought that it was a Pokemon clone that wasn't entertaining. It really took away from the viewers, and it was just boring. After watching it a few time, I decided that I'd never watch it ever again.
Even though I liked the Tower of Druaga game (and its sequel, The Return of Ishtar), the anime was awful. I was disappointed that Gil, the hero of the game, was relegated to an insipid side character (and Ki was dead). Jil, the new hero, didn't strike me as too interesting. Fatina is a shallow love interest at best, and evil at worst. Kaaya was better, and at least they game someone a connection to Gil and Ki! (She's their great-granddaughter - since this takes place 80 years later, Gil is probably at least 95.) Neeba was just annoying. And we barely even get to see Druaga. That had to be a huge letdown! Look up the game artwork for Druaga - he looks awesome!
I really didn't like the anime Mario movie. For those who don't know that it exists, it's called Super Mario Bros: Peach-hime Kyushutsu Dai Sakusen and came out in 1986. While it is definitely much better than the infamous live-action Mario movie (and has better animation than the Mario cartoon), the anime Mario has a lot of flaws. The Koopa Troopas in the movie are hideous and look rather birdlike - definitely far from the cute Koopas of nowadays. Though I get that back then, Koopas were ugly and walked on all fours - and were always evil. (I'm a huge fan of Koopa Troopa - I have a plush one at home!) It also doesn't make sense that Mario and Luigi work in a grocery store. It was also hilarious hearing Bowser's voice (in this film, he is voiced by Akiko Wada, a woman.), which is pretty bad, but hilarious nonetheless. But the biggest letdown is the ending. When Mario rescues Princess Peach, it turns out he can't have her. The stupid dog that followed them around turns back into a prince named Prince Haru and proceeds to tell Mario that he and Peach are engaged. Mario is very upset about this, and I think you can understand why. He spent all this time trying to save Peach from Bowser and he CAN'T have her just so some uncanonical character can? WTF? Luckily, Nintendo has pretty much ignored Prince Haru's existence (by never putting him in the games) and made sure that Princess Peach is always paired up with Mario. (I do admit that I love the love song in the movie.)
Which anime do you dislike even the Japanese version of? (Just don't name Pokemon - I don't want to see this post get locked.)
