Even though anyone who's ever seen a movie will know everything that's going to happen, there are some pretty good jump-out-at-you surprises in SWIMFAN. Having the hero (Jesse Bradford) spend so much time in the pool wearing nothing but a swimsuit and goggles adds to the atmosphere of vulnerability and otherworldliness. Erika Christensen (Traffic) is very effective in her retro good-girl dresses and high heels and uses her baby face well to switch instantly from innocence to obsession. Overall, though, the movie is a forgettable retread of more effective thrillers.
