No, the plot is nothing particularly special, and the writers don't bother to be too terribly clever, resorting to the cheap laugh more often than not--usually obvious puns and corny innuendo. But the characters are hilarious, and very well played by a slightly second-string cast. Why are there no top-line actors here (besides McKean and possibly Perabo and James)? There's nothing wrong with these performers at all--they nail the characters perfectly--but all of them resemble much bigger stars, which is rather distracting and just makes us wish there had been bigger-named stars involved. (Where's Kirsten Dunst when we need her?) But never mind, this is a brainless comedy that at least keeps us laughing fairly steadily with wry observations and a vicious sense of humour. The story's main twist is so glaringly obvious from the beginning that we're not remotely surprised. And at least it's a diverting way to spend 90 minutes, even if we forget everything immediately when the lights come up. But with a tighter script and a more stellar cast this could have joined the pantheon of great teen comedies.
