I'm starting to stretch "controversial" but here's what I got left.
-Fafner is an absolute snore.
-Black Blood Brothers is one of the best vampire anime.
-Gankutsuou is boring.
-Gunslinger Girl has an awesome core concept despite its apparent ridiculousness.
-Kobato made me want to kill myself after 20 episodes.
-Michiko to Hatchin was terrible.
-Midori Days is charming, funny, and awesome.
-Moribito: Guardian of the Spirit is overrated.
-Ninja Nonsense is a fucking riot.
-I hate all yuri shows
That's all I got left and probably half don't qualify well.
Cutting me somewhat deep with the bolded. Cutting me really damn deep with the underlined.
