Just finished Neon Genesis Evangelion. It's a mind [censored] at the end. It made me think too hard.
As already reccomended watch End of Evangelion, it won't really make more sense than the actual ending, but it's pretty to look at.
My favourite animated film probably, easily in my top 10 overall films.

Watched the two avaliable episodes of Hanamaru Kindergarten recently (because Gainax can do no wrong), the second episode had the best http://www.youtube.com/watch?v=7rFQL5nWTR0 ever, Gainax should scrap what they're currently doing with the show (not that i think its bad) and make Macross with lolis.
