I recently started watching Angel Beats! and am now caught up to episode 12.
With this in mind, I just put out
a blog entry looking at what I think is the real central story of Angel Beats! I figured some people here might like to check out that tentative series review.
It's very interesting what Maeda has done with this anime. So far, I'd probably rate it somewhere between 7 and 8/10 overall.
