After watching The Mist show I thought it was utterly terrible. The premise of the movie was so well done and to be honest the show didn't capture that one iota. While I appreciated that they went for the "Mans Struggle and what they will do when desperate" angle it just didn't work on any level. It was so disjointed and most of the time the acting was sub par. I really didn't care for any of the characters so it was hard to get invested for 10 episodes. All the religion connotations were silly really.
I actually loved the movie. It was a shock movie with monsters, suspense, gore, claustrophobia accompanied with a huge dollop of paranoia and despair but the show really didn't compare.
