Somebody told me I need to write more so people don’t assume wrong things. The two people in involved in the mess are production manager Mimori Keiko(disgusting otakus die) and Gurren Lagann producer Takami Akai(2ch is like an anus).
The current flow of events:
1) Gurren Lagann ep 1 airs and most people love it
2) Mimori Keiko sees comments from the small minority that did not like ep 1 and says she does not want to deal with digusting otaku anymore and they should all die
3) Takami Akai replies that “2ch is an anus. It’s full of brainless trash that think they are superior to all.”
4) Episode 4 airs and there is a riot on the net over the bad art
5) Mimori Keiko comments that “That episode is something that only a pro would appreciate. Amateurs that don’t know what they are talking about should not comment about it lol.”
6) People notice old comments made earlier in the month about disgusting otaku.
All the comments from the Gainax staff were personal comments made on mixi, a social networking service. The actual posts can be seen here and here.
Not really related but Gainax apparently also put up a Gurren Lagann comic two days ago featuring the mascot from Precure 5 getting shot by Yoko, and Toei got pissed off.
