This is without a doubt one of my favorite animes, since it is really funny and sad, and i recommend everyone who have not seen it to see it no matter what anyone else says.
Story: 9
Well to start of with the story, even though the story is quite good there is not so much to write about. The general story all in all is that in a state before afterlife, the purgatory, is a school where high school student comes if there is something they not managed doing in their life and ended up there to make it up. And there in this school exists a resistance group called Shinda Sekai Sensen (Afterlife Battlefront), and their goal is to fight against God since they don't think anyone would have that kind of unfair life that they did live through.

This is Angel Beats! most outstanding part, since it is GORGEOUS! I fell in love with it from the first episode. If you watch it you will experience a new world of animation. The characters are very well drawn, the surroundings are awesome, and the concerts were magical.
You will love it.
Sound: 10
This is also one great part in Angel Beats! since they have really great voice actors like Kamiya Hiroshi as Otonashi and Hanasawa Kana as Kanade and many more. And the soundtrack was really fitting for the right moments. Girl Dead Monsters (The rock band in the anime) was great and i can't stop listening to them now a few months after it ended since they are one of the best bands I've ever listened to.
Character: 10
The one thing that most seem to complain about in this anime is the character development and therefore doesn't give it a high score. I can agree with that it is one of their flaws but even so, the characters themselves make up for since they are unique in their own way and they are awfully funny and a character that everyone can't hate is TK, the dancer who every now and then with a random phrase in English. He alone is worth giving a 10 to.
Enjoyment: 10
The thing I liked most about this anime is the comedy since it is my kind of humor. And some episodes made me laugh clean through. And the sad parts really made you shed a tear or two.
Overall: 10
An awesome anime that i recommend to everyone that looks for something to watch.
