Easy.
5.) InuYasha - I used to actually like this show. And then I noticed that it was just never going to end. And on and on it went, hundreds of episodes of fluffy filler... and suddenly it just ends without a proper ending. FUCK THAT SHIT.
4.) Bakugan Battle Brawlers - Nuff said. Another fucking Beyblade/Yu-Gi-Oh/Pokemon battle-shit rip-off. Well, you can go FUCK yourself.
3.) Full Metal Alchemist - Just a really annoying show. Bothers me quite a bit. And it's successes with mainstream audiences (a.k.a. the uninformed masses who think that things like FMA are really "hardcore" anime... stupid tit-fuckers) ensure that you can't escape it's influences no matter how far you try to run...
2.) Dragonball GT - Dragonball Z was ok... sorta. When I was 8. So was Dragonball. But GT... ughhh. Fucking SHIT. Worthless in every sense of the word.
1.) Naruto (Shippuden or otherwise) - That show is the most fucking worthless piece of shit to ever crawl forth on the face of the Earth, and it's very existance is offensive to me. Plus, because of stupid fucking emo Sasuke, you can't go to an anime convention without seeing swarms of Naruto fans runnning around, mis-pronouncing all the names, and squealing about how "Sasuke is sooooooo misunderstood!!! But I could love him!" ... Makes me want to fucking slit my throat.
