(Rob Zombie's) 31 (2016) 
I'm unsure about
31 at this very moment in time. On one hand, it has some very atmospheric and well shot scenes, on the other hand, as soon as anyone talks the dialogue is so awful it just ruins it all. It's also very mean and nasty but I'm sure that was the point.
However, possibly Sheri Moon's least annoying character performance, and a pretty good chainsaw section in the middle! But I doubt that I'll ever watch it again!
Final thoughts, all the way through the Doom-Head opening sequence in B&W I was thinking how cool and ballsy would it be if the entire film was shot like that.
