Is that okay?
It's probably better than having an actual showdown with God. _The Devil Lady_ could pull that off, but it's super risky. It's very easy to have a broken moral or metaphysical story, and I think _Angel Beats_ is better for choosing not to go there.
What's my recommendation?
It's worth a watch. _Angel Beats!_ uses heavyweight parts without becoming overbearing. It's not particularly challenging despite looking risky.
I wouldn't watch it if you're in the middle of a deep depression, but it's a good pick, I think.
