I enjoyed most of this film up until the messy resolution. The plot doesn't play out in a supremely satisfying way, which hampers the overall impact. The performances are all fine and there's some good suspense throughout. Gwenyth Paltrow's character makes some odd choices and seems generally clueless throughout, but also makes some remarks that appear as if she knows things. It's rather confusing. A Perfect Murder kept me invested all the way through with its sleek and stylish story, I just wish the ending had been a little more thought out.
