Yeah, I love this series. I've always been a fan of Key anyway and I remember being so stoked when I heard about this new project. For what it's worth this ranks in my top 3 Key works (along with Clannad and Rewrite, the latter of which sadly doesn't have an anime adaption(yet...?))

If you've seen other Key works like Clannad, Kanon or Air, you probably already know that they tend to enjoy mixing comedy with tragedy, often whiplashing you between the two very quickly. Whilst these elements are certainly present in Angel Beats, and whilst the pasts of some of these characters are still pretty horrible and tragic, I don't think the series generally wallows in it as much as other Key works perhaps did.

The series has a nice mix of action, comedy, music and drama and it works really well. It also has TONNES of characters (A trait it shares with Little Busters I guess) which sadly, due to the series only being 13 episodes long, don't all have time to be developed to their full. Still, they are all a fun and silly bunch generally, and watching their antics is very enjoyable indeed.

Finally some good news for anyone who wanted more. Key have finally announced that an Angel Beats Visual Novel will be released in 2014. By the looks of it, it will be released in separate chapters (or beats), but hopefully this will give people a chance to learn more about the characters that didn't get much screen time in the anime (well, assuming it ever gets translated :D)
