@mage_goo Angel Beats! was amazing. Yes it was short, but it was meant to be. They're living at the same speed as the anime basically. And the manga Angel Beats! Heaven Door answer every quetion you might have since it happens before Otonashi joins.
Angel Beats! plots mostly happens because they are so in a rush they never stopped a second or two to think and try to actually talk things with Tenshi. Something only Otonashi does since he actually has a more mature viewpoint, and then break the deadlock.
Charlotte wasn't bad, but it wasn't at the same level. The plot twist was so brutal it felt like a different anime. I liked the last episode a lot, but the two before it were at best a 6/10.
