It's a typical normal-man-gets-into-impossibe-situation thriller that follows the blueprint for the genre. If that is what you're looking for than that is what you'll get. As long as you don't expect the world out of it you'll be fine. Oh, and Liam is actually close to being 66 and if you ask me it doesn't show. I'll hope he does some more movies.
@finfan His age was also on my mind. Especially since the character was 60 years of age :)
