wig
I looked up pics of the actress online, just to be sure she didn't have some disease or something. She doesn't. She has a full head of beautiful, natural hair.
Unless there was some plot point I missed, I can't imagine any cause for putting her in a wig throughout the movie. It was so obvious and fake looking.
I liked the beginning and middle of this film. It really seemed to be going somewhere interesting, but it lost its way in the end.
