Everything was visually lovely - exquisite production value, but characters relied too heavily on the idea that depressed, self centered people who let their angst overwhelm their consciences are somehow beautiful. It's not endearing, and it's unhealthy to encourage ppl who have depressive tendencies to wallow in them and become self destructive.
I'd say watch it but only if you can keep yourself from getting invested because otherwise you'll be stuck with a bunch of very sympathetic peripheral characters and a pair of main characters it's really hard to root for.
