Good story, Not enough for a whole film

It's fun, it's light, [but] it has a hard time when its tries to get heavy.

While it doesn't offer any answers, it both thrills and makes you think.

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.
