The only strong objections I have are of the Evangelion dub, Haibane Renmei, Violence Jack, and, for its artistic merits and contributions to animedom, Mars of Destruction. I'm sure there's alot here that people can get extremely pissed at and I took him alot less seriously after he listed the Eva dub, but some of the choices here are fair game when it comes to notoriously bad anime.
I will say though that I like how the dude here is more of an otaku Will Sasso than a neckbeard with a whiny voice like some of the anime commentators out there. Looks like an anime commentator you could have a beer with.
