episode 4 of Gurren Lagann yet? Besides a move away from the non-stop action to what could be described as the plot, the episode had another jarring difference... the animation quality.
This episode actually created quite the scandal back at its initial airing over two years ago. Guest directed by Osamu Kobayshi, who you might know for his work on BECK, the episode received plenty of negative response, particular on the dreaded 2 Channel. Gainax co-founder Takami Akai was so incised by their complaints that he took to the board himself, and insulted said fans.
The insult? Well, I'm sure it works much better in Japanese, but he basically asked the dissenters to put their face near an anus and breathe deeply.
The scandal was so large that Takami stepped down for Gainax as a result of it all. Though, as time would eventually indicate, he is back in the fold today. There you go, there's the news from the way back machine.
