I did not understand this movie.

I know I'm late, but this movie didn't make any sense.

1. Who was in the crate that Larry and his wife found at the beginning of the movie.
2. Why was Larry put in the crate and then hidden in some closet at the Chase house. What was his purpose there.
3. Josh left the house and came back that same night. Collector dude seriously set that many elaborate traps in that short amount of time?
4. How the hell did that dog know exactly where to go upstairs to get Josh and Karley after his failed attempt at nipping at her feet while downstairs.
5. Josh jumps in front of a speeding cop car. What did he think was gonna happen with that. Duh?

You'd think this movie was written/directed/edited by a group of 8th graders. What a waste of time.
