Like many low budget movies, WINTER'S BONE has some rough edges, but overall, it's a very well-made and gripping film. Based on a novel, the story is very involving. The first thirty minutes or so are a little rambling, but once it starts moving it really keeps your attention.
There's a weird mix of acting. The movie takes place in the Missouri Ozarks. Some of the characters are good actors but not at all convincing as being from the area (like the lead actress). Some are clearly local extras who are convincing but not good actors. A few are both (mostly older actors).
There are some rough technical edges as well, focus seems to be a moving target in a few shots, and at other times the camera is in the wrong place. But overall I would recommend the film to fans of independent filmmaking.
