charming little story
26 October 2001 | by babeulousSee all my reviews

This movie was fun. I don't know why everyone is ragging on it. Deserving, nerdy guy gets the girl and saves the world. Nice salutes to movies of the '40s. If the plot's weak, it's because there's not much conflict, no diabolical scheming bad guy. The characters are all sweet and real enough that you care about them. Ms. Basinger is pretty, but if you want to see her do sexy, see _Cool World_.
