At first I kinda felt it was going a bit slow ,, but it picked up in the middle and I could feel the mystery and thill pile up and as a plus it had quite the unpredictable ending , so overall you can actually say it was a very good watch.
The cast was great,, even if "at times" there was a bit coldness but still they were good .. from the young Jack Black look alike :D Emile Hirsch, which was good but sometimes awfully calm, to Andi Matichak, which I liked very much in here.. the kid though was just okay...I think needed a bit more weirdness in his act.
The script was good ,, directing was fine and maybe needed just a little speed up ,, but my problem , well my only problem was with the cinematography !! I mean it is a movie about a cult and the devil , so they should have been some more money spent in that department, I do believe that devil looked ridiculous ..
Anywy, the movie is recommended ,, so watch it.
