Felt Somewhat Incomplete
While it's understandable why Sam would react very emotionally to this situation, I still expected there to be some backstory as to why this was so important to her. I guessed it was because she went through something like this as a child, and it's resurfacing.
The ending shot was interesting. In a way I'm glad that they made their interaction somewhat realistic, but some of Sam returning Nate's feelings would've been a nice ending, at least to tie up some loose strings.
Also, how did the camera get inside the house??? Did the man find it on the car seat and bring it back in?
Overall not as bad as I thought it would be.
