This series is a must-watch for fans of all of Key’s work.

while Angel Beats! is guilty of using that formula of starting out comedic before becoming dramatically heavy, the sheer absurdity of its comedy and the sad layers underneath make this a better example of that trope. Brilliantly animated and themed around the unfairness of death, as well as how precious life really is, it would be a hard task to leave this anime with dry eyes.
