Don't Let Go is a frustrating film. It has a solid premise and a stable of consistently reliable actors, yet fails to use its seed of an idea to sprout more than a sapling of a film. In the post-show discussion of the six citizens of City of Geek present - the standard four of us and two friends - we came up with several far more interesting ways to use the set-up than the film itself did. That's why we found the Jacob Aaron Estes written and directed sci-fi/horror/thriller to be so frustrating. Don't Let Go doesn't allow itself to dig into a great idea in any sort of more-than-basic way.
