ATTN: fast forward to the end!!!
Ok, i did like the movie, so I want to try and get it a few extra stars AND save the sanity of some viewers......once the arguing gets to you, fast forward to the last 20 min. You really won't miss much that adds to the value of the overall movie ( although I enjoyed both the confrontation with the kidnapper and the officer pulling them off the road). I would say if you can make it to the gas station scene, that's about all you really need to know to understand the last 20 minutes.
The last 20 min. at least, imo, "make" the movie and give you enough suspense to overlook the annoying. I think the concept WAS really good, especially when compared to a lot of the other "single camera, documentary style" movies that have swarmed up in the genre lately.
