The phrase 'when bad things happen to good actors' usually applies to bloated Hollywood fare, but it can also equally apply to much more modest productions like the would be thriller "Retreat." Overall, after a neat set-up, the movie suffers from a fatal case of indecision, giving its talented cast little to do, except for one scene where a character is glad he played a lot of Operation as a kid. Otherwise they sit around and shout at each other while waiting for the drawn out climax to happen. Whereas I can understand Jack being something of an enigma since he is the key to the movie, the same could not be said about Martin and Kate. She is a writer and they suffered an unspeakable tragedy of some sort and that is pretty much it, which makes it that much harder to care about what happens to them.
