I watched this movie only because I'm a huge Norman Reedus fan, and this was one of the few movies of his I hadn't seen.
One of the biggest problems with this movie was the pace. It spends forty minutes just showing Senga (mom) and Nat (daughter) bickering and arguing, which definitely does nothing to endear Nat to the audience. Then it briefly picks back up... only to slow down again. This definitely isn't something I'd watch on TV, just because I probably ended up skipping through an hour of this hour and forty five minute long movie.
Another problem was actually -and I hate to say it- Norman Reedus's character of the 'Recovery Man'. He pulls the role off well, but... well, there really wasn't enough of a role for him to do much with. He follows the group along, okay, so far so good... But then you get the impression that he's been following them for years as a tow-truck driver, but never gets anywhere, and just happens along Senga and Nat, and decides to sort of follow them, but not really. Then finally at the end, just as his character starts to get sort of interesting, boom. Movie over.
Also, as far as this being a horror, or thriller... There really was no substance to it at all. There's nothing remotely scary, or even chilling. The camera work was amazing, and did give off a creepy vibe, but the story itself was... very blagh, is the only thing I can think of.
Normally, I would say not bad for it's genre, but again, it really doesn't fit into a genre... Comparatively speaking, it wasn't horrible (especially compared to some of the trash passing itself off as good cinema lately) but it just didn't do anything for me. Again, it was more of a 'when is something interesting going to happen?' rather than 'what's going to happen?'.
