"Angel Beats" was at best an average show. The show had potential to be really great, but was severely flawed in character development.
The supporting cast was far too large and had too much presence throughout the series. This left little room for developing the three main characters (Yuzuru Otonashi, Yuri Nakamura, and Kanade Tachibana), and led to the inevitable let down at the end of the series where we see the emotional climax. It was difficult to feel emotional at this part because the series did a poor job making the viewer develop an emotional connection to the characters. With more time spent developing the main characters, this could have been much, much better.
For my concluding point, the main problem was that the series tried to accomplish too much in a short amount of time, and this caused each arc to feel very mediocre. Perhaps if the series was longer it wouldn't seem so rushed, but a good 13 episode series is absolutely doable. Take "Anohana" for example. There were two main characters (Jintan and Menma), and a small supporting cast, which left plenty of room for strong character development and made the ending so much better.
Overall a decent series. 6/10, would recommend.
