If you're new to Japanese animation, FLCL is probably not the best way to make your way into the genre.
The good stuff
Diebuster is a series aimed at fans of the original who still have a place in their heart for modern anime.
I've seen the old series and films twice, I've watched all the newer features, but still Evangelion is a lot of waffle to me. In a way, I do appreciate the extended lore and dedication that went into this series, but I simply don't care enough about it to sit through the lengthy explanations and excessive melodrama. Luckily, this latest (and supposedly final) film has more to offer than just lore and drama.
Shinji is still a shadow of his former self, blaming himself for not being able to protect humanity. He ends up in a small village, among some old friends, where he learns to appreciate life again. He pulls himself together again, right in time to join Wille in their last attempt to deflect another impact.
This final Evangelion is a film with lots of ups and downs. The animation is exquisite, the action scenes are stupefying and a lot of the imagery is intriguing, but the drama drags the film down and the lore is simply too nerdy for me. I'd prefer Eva as a simple mecha action flick, but I know most people won't agree with me. Not a film that will bring new fans to the franchise, but existing fans will have a lot to chew on. A worthy finale.
