Three way tie between Dubs, Filler, and those terrible endings that resolve nothing. The worst dub I've heard so far is Rurouni Kenshin (he sounds like he's either a young girl or a boy in the middle of puberty), worst filler of course is Naruto (I mean they actually had to start a new series just to move away from it!!), and I'll agree with everyone else and bash Inuyasha for its horrible ending (though Flame of Recca's also irritated me quite a bit, and Histories Strongest Disciple Kenichi stopped right before the best part). These three things are why I mostly just read manga now.
