Real disturbing stuff! But in a good way. I think the film would've benefitted from showing less Nic Cage, however the world is always the loser in that equation.

Less Nic Cage = Higher movie grade.
More Nic Cage = Higher Cage Scale.

4/5 on the Cage Scale. He's doing a great job in using his massive talent to create a performance that is unbearably creepy and unpredictable.
