This is just to backup your memory after you've seen the serie, so there's NOTHING new for evangelion' fans. It's not bad to say as well that this movie is very well done: scenes are in a particular not-serie-chronological order that's enjoyable and make you get back memories from the serie you watched. If you're going to see 'The End of Evangelion' watch this movie too, it won't hurt you for sure ;)
