I liked the trailer from the jump, then it hit a turn and I thought, "Ooh, it's a ripoff of 'The Game', I'm in." And then the trailer proceeded to show the rest of the film except for the final decision.
Still, an interesting looking flick and I'm always a fan of the mid-low-budget thriller so I'm hoping it does well. It's from the Catfish guys (who also did Paranormal Activity 3) but I won't hold that against it (I hated Catfish.)
