The many time shifts reminded me of the book "Slaughterhouse Five", by Kurt Vonnegut, but this movie was not as confusing as that book. Using those time shifts into the past in order to reveal some plot twists kept it interesting. Showing the spinning hands of a clock in order to alert the viewer of the upcoming time shifts did get old though. Carla's (played by Kristin Minter) constantly repeated comment "this will be better than what we planned" (or some variation thereof), which she used whenever things went wrong, also got old quickly.
John Ratzenberger's performance as P.I. Clay Fairfield, was refreshing in a non-Cliff Clavin role.
I must have missed something, but can anyone e-mail me to tell me how the body got out of the trunk about 3/4 of the way through the movie? (when shortly after that, Rachel Avery found it laying alongside the road).
