Query: Let down!

Okay. I was so excited about this movie when I saw the trailers. The idea that the piece was going to be happening "in real time" seemed like a really cool and unique way to shoot a horror film. And....for about the first 2/3 of the film it was. But that is where it all fell apart. The ending of the movie was so out of left field and so incongruent to the rest of the film I literally had to rewind it to make sure I didn't miss something. Sadly, I didn't.It's too bad because the acting and premise were very good. The ending was just a sad letdown.
