Fullmetal Alchemist: Brotherhood: I actually thought it was very good, maybe even better than the first one until the end. What the hell? It felt like something of a bad fanfic wrote by a 15-year-old. Yeah, maybe the original 2003 series deviating from the manga halfway through wasn't a bad idea after all (hey, Arakawa herself didn't mind).
Gurren Lagann: I have something against works abruptly changing tone in their final episodes. Gurren Lagann is no exception, and it's probably why I never bothered watching the final four episodes (also uni constraints and some internships so I could save on some credit but I digress). Surprisingly, Gurren Lagann pulled it off neatly.
Sekirei: One of those shows I watched purely out of being a massive guilty pleasure. I had no idea how I even ran into it.
Love Hina: I have no idea why people even liked this show. ._.
School Days: tvtropes said "Sensitive, idiocy-intolerant or squeamish viewers, beware!". Man, they were accurate as fuck on that second one. I hated every character so much a meteor could land and kill them all and it would have been a happy ending.
