Well, we saw it last night (lady Avenger loves comedies, which is about all we see unless it's some kiddie show for the grand daughter). I thought that there were a few humorous moments in it (Kevin What's-his-name yelling, "I'm about to go Hercules on your asses," brought a grin, though not a real laugh), and the guy who played Leonidas, aside from being too short, looked the part pretty well and had the voice down pretty well.
It ain't on my "Run out and buy the disc," list, though.
