Heretic
Rewatch was substantially better!! Sooo many little details that make the plot just a little more believeable which goes a long long way. Like for example Mr.Reed notes the scar on Sister Barnes' arm early on. Just makes so much more sense on round two. Only big flaw is Mr.Reed has no motive for what he's doing and has absolutely nothing to gain which really throws off his whole incredible set up he has going on.
