The Informers
Im not going into detail of how bad I thought this movie was, because it doesnt deserve that. Over-stylized dreck with characters that were beyond easy to dislike, contributing to it being so bad that I didnt turn it off just so I could see how it ended, which was so bad I laughed. Billy Bob Thornton was totally miscast, Winona Ryder just seemed out of place, and I kept asking myself why the rockstar was even part of the movie.
The only even half decent part of the movie was 3 performances. Kim Basinger was good, if not over the top, as a pill addicted divorcee who seemed to wish she was 30 years younger. Chris Isaak was surprisingly good as a rich, alcoholic, womanizing father (well, maybe not surprising

).
Brad Renfro stole the show though in no more than 10-15 minutes of screentime. I thought he was good in a movie a few years ago 10th & Wolf, but this was easily the best performance of his career. I think he couldve been around for a long time as a very good supporting actor had he not died.
Max Payne was probably the worst movie Ive seen from 2008. The Informers, thus far, has been the worst movie Ive seen from 2009.
