We picked up a great review from Mark Leeper. You can read it here.

This film will bring back memories of films like MEMENTO, 21 GRAMS, and some time machine stories, but it is really very different. Nonetheless, that puts the film in very good company. If a film can do that, it is probably very good. This one is worth seeing. After seeing the film with a friend, be prepared for a discussion of what was really going on and if it all hangs together. I rate FISSURE a 7 out of 10.
