In a postapocalyptic world EVAs fight angels and teenagers have weird problems.
Not an Evangelion fan or even casual consumer this movie is absolutely indecipherable. From a structural standpoint it seems to follow a strict back and forth between possibly comedic situations in the group of teenagers piloting the giant EVA robots and some Überfights between the "Angels" and them. Some of the visuals are breathtaking especially during the fights. As the whole film seems to be part 2 of 4, there is no recognizable development in classical dramatic form. (It doesn't have to, but the way they've done it here is remarkably boring)
Interesting is the terminology borrowed from all the religions alike - it seems a little upsetting at first, but actually it seems like quite a clever idea.
