The first half of the anime focuses on fighting the angels that are invading earth. Then the second half focuses on the psychological problems of each of the characters. Your going to be asked what is the point of living and what is your purpose in life. The second half of this anime is kinda depressing.
This anime does have a lot of action, and the animation for the action is very good for the 90's, but the studio ran out of money during the second half and it is very obvious because the animation drop's pretty significantly.
The characters are overall good. I have a problem with Rei though. She doesn't really change through out the anime at all. She doesn't really have a personality. but there is a answer for that though. Asuka can come off as pretty annoying in the beginning, but she brings out the other characters personality, which was needed. I don't want to tell you anything about the main character though.
Overall I would totally recommend this for anybody who is ready for a roller coaster of emotions. Also watch the end of evangelion movie, it will answer your questions at the end of the series.
