7. Jennifer Lopez
Over the past twenty years or so, Hollywood has tried really hard to make Jennifer Lopez into a movie star. But she's just not. With very little exception, almost every film she's starred in has been a disappointment, both critically and economically. We can argue the merits of her as a singer and entertainer, but as far as acting goes, I'm afraid it's a bit of a lost cause. While she was good in Serena, a huge part of that has to be down to her singing ability and the natural draw of the tragically murdered entertainer. The push for her thrive as a romantic lead hasn't gone as well as anyone had hoped, and year after year she comes out with comedies that aren't quite as charming as they think they are. The Back-Up Plan? Monster-in-Law? Please. Stick to music. Last Decent Movie: Out Of Sight (1998)
