I enjoyed Sinister. Ethan Hawke did a great job in the movie, and the bad guy looked freaking cool, too. I even like that they didn't chicken out at the end, where they...hey, you're not going to trick me into giving away the end! Nice try, though!
The second one is coming, and they released the short teaser for it, and the full Sinister 2 trailer comes out on April 9th.
