Problem with this film is the lack of character development. I know it's just a light comedy, but there needs to be something compelling about the characters for us to like them, root for them, or even want to continue watching them. The main character (the girl) is not written to be likable, and the actress does little to save things. Tyler James Williams is a good actor, but he has nothing to work with. His character is just "a nice guy", but has no more depth than that. He cooks for and attends to his girlfriend and never finds anything she does unappealing (no matter how horrendous), plus he is great in bed. This is every female's dream boyfriend, but not a real believable one. Hard to get to the end of this one.
(Also, Tyler James Williams looks nothing like the actor who plays his brother. Poor casting.)
