Short summary:
One of the worst movies I have ever seen, seriously, don't waste your time.
You are so annoyed by the actors, that you can't even focus on the movie. Pretty much throughout the entire thing, I wanted to punch everyone in the face, especially the two lead characters, Caleb and Sam.
There is a lot of high pitched screaming in the movie, 89% arguing, horrible acting, I gave it a 2/10, and that's being generous.
You have been warned, stay away from this movie.
