Review from a Non-Critical Role watcher here:
Spectacular show. Absolutely brilliant and a beautiful piece of art.
If you are a tabletop gamer, chances are - you will love this show. (As long as you don't mind some crass language, a tiny bit of nudity, and lots of gore and violence.)
It takes itself seriously enough to be a surprisingly enthralling storyline, while taking itself lightly enough to pepper lots of humor in - including plenty of geek-service humor. (the Murder Hobos haven't returned yet!).
If you aren't into table top games but enjoy fantasy stories - still give this a go. Like any show it takes a bit for it to come together, but it pays off - plus you can enjoy the beautifully done animation in the meantime.
Beautifully executed, and I can't wait for season 2!
