I have Always been a fan of Dennis Quaid, and then theirs Ben Foster who's been doing tons of great work taking lead in this one. They both do fantastic jobs !! Ive watched it twice, once alone, once with the GF (Who is not even a sci fi fan), and she loved it too !!. Second time watching I noticed even more, it kept me very entertained both times around. Definitely worth a watch, maybe even two !! I would put this in the Apocalyptic, Sfi Fi, Psychological Thriller Category, but I think any genre lover will find this entertaining.
