Alright, watched a few more of them...I' ll list why I think they were " banned" from theaters.
1) The Abandoned - Gruesome Murder scene
2) Reincarnation - Two children are killed, on screen.
3) Dark Ride - A child is gutted on screen.
4) Gravedancers - I couldn' t see anything, this is no more horrifying then Friday the 13th.
Unwatched:
5) The Hamiltons - <pending assumption>
6) Penny Dreadful - <Pending Assumption>
7) Unrest - Strong assumption is that since the trailer touts this being the " first movie to use real dead bodies on screen" I think that would be enough.
8) Wicked little things (might have the name a little wrong) - I assume some kids get killed on screen, but aside from that nothing really.
