An amazing thing about Catch Hell is how unexpectedly *watchable* it is. I really figured it wouldn't have staying power, yet it coaxed me in.
Others have commented on the film's modest strengths, which are; decent writing, good acting, good pacing (the scenes that seek to capture the long waiting of a hostage situation like this don't feel interminable), good (if elemental) character development, good editing, interesting scenario.
And, amazingly, the final scene (which ingeniously plays over the end credits) struck me as a profound redemption tour-de-force. Rarely have I seen such a cosmic message writ so bizarrely. I can think of one other example, off the top of my head, that comes close. And, when I say "redemption", I don't mean the redemption of a person. I really mean the redemption of this film from being a mere low-rent action/horror snack. I'm sincere about this: It says an important thing about the nature of grace; that you might encounter some at the very bottom of a very deep, very dark pit.
Worth watching, even if only because you're fascinated by the promise of smart low-budget stylizing.
