I had to suspend disbelief quite a few times to be able to get into this movie. There are so many movies and novels about "found money" that I can't imagine that many couples would be stupid enough to quit their jobs, and start spending it immediately and without regard on a $70K Range Rover and a house full of new furniture. Everyone knows to lay low and spend it slowly and not attract attention. The bad guy is able to track them though the presumption that they would immediately buy a new car, and even though he is new to town somehow finds another bad guy who not only sells guns but also happens to have the keys to the DMV(!!!) (What!?!) so he can pull the records on all recent "cash" vehicle purchases. And for some reason the couple gives the wife's mother half the money in a Christmas box for safekeeping!?! Why? Never heard of safe deposit boxes? Floor safes? Jeez.
I still don't get why they couldn't get another actor to play Sean Bean's brother. Stunts like that just pull you out of the story, since you become focused on how they made two of an actor you know there is only one of...
Despite this stuff, and more that made me want to smack the writer around, I did get into the story. There were some actual good moments where the twists were unexpected, and Hemsworth and Bean are good actors that I like.
The movie has no moral center, though, and virtually everyone in it is creepy, mean, and stupid or self-destructive on some level, including the bit characters, the couple, and the mother. By the end I was hoping they all died. Very jaded look at the human race. I get why people like it and others don't. I think I am right in the middle. Two and a half stars since I did get into it, but I really want to give it two for not trying a little harder. I have a lot of problems with the tidy ending, as well. I would have driven that car off a bridge, rather than involve someone else, but again... just sloppy.
