I just finished watching the movie for the first time. *SPOILERS*
I didn't know much about it beforehand. Just that a family moved to an empty house.
I enjoyed it.
My four favorite parts:
1: Acting. Everyone did a great job and it was a treat seeing KC in a thriller. Very nice!
2: It was a joy watching such a movie where the cute boy remained a cute boy for the duration of the film without changing to a monster, becoming an unstoppable mofo killing everyone, or in general changing in character in such a short term. He felt REAL.
3: The "accident" of the blond girl at school. Very well done.
4:I LOVED the action scenes with Kevin using the shotgun. LOVED THEM.
All in all I thoroughly enjoyed it and I am glad I watched it.
