I really like Alan Tudyk. Tucker and Dale vs Evil is one of my favorite movies and he's so good in it.
This show lost its way after season 1 though in my opinion. None of the characters grow or change in any meaningful way. Darcy, the mayor, and especially Asta are just annoying at this point. And Tudyk's characters "Autism + Tourettes" routine got stale very fast. An Alien that can watch a YouTube video and learn any medical procedure immediately on an alien (to him) species can't figure out how to change his speaking and mannerisms. It was funny at first, but got real stale, real quick.
