Halfway through the first season and it's a lot of fun. I only decided to give it a go because of Alan Tudyk and he definitely carries the show pretty heavily but its got an off-beat charm and comedy to it that I enjoy. It's a SyFy production so don't expect AAA production values but it doesn't really need them for the story it's telling.
The first season just wrapped (10 episodes) so it's prime for binge-watching. Worth checking out for sure.
