This film succeeds because of Jesse Bradford. I remember him from Bring It On (another excellent performance), but it appears he's done lots of things. He's a great lead actor, and I can see him filling Tom Cruise / Ben Affleck style roles in a few years' time.
The film itself is a fairly respectable effort at a Fatal Attraction style relationship, with teen-thriller-genre elements of the misunderstood wierd guy, the new girl in town with a secret past, and so on. I can only think of one vaguely surprising moment (with Josh, in the pool) - otherwise it's fairly predictable, but enjoyable all the same.
Watching it, I couldn't help but wonder why the school's best swimmer and most attractive guy didn't have a bigger circle of friends (Josh the jock, Randy the drip, and a black girl with a chip on her shoulder (what an original character..).
Also, why would he be tempted by a girl who isn't quite as attractive (or as nice) as his girlfriend? - but I know that's often the case in real life, so I can let that go.
Finally, Jesse didn't need the whole 'troubled teen past' - in the places where it was used, it wasn't really necessary - and although I'm no fan of the family values lobby, I am thoroughly sick of the single-parent-family that seems to exist in every single movie these days. It's just a lazy way of adding to teen angst, and avoids the need to write convincing two-parent scenes.
Swimfan is fine, but is only really a stepping-stone movie onto bigger and (hopefully) better things for the lead actors.
