There's one simple reason we watch comedies, and that's to laugh. So, let's face it, a comedy doesn't need a perfect plot, sharp editing, or great camerawork to be considered a classic. But that doesn't mean movie mistakes are any less annoying. Great comedies like "Groundhog Day" and "Anchorman" can easily brush off the occasional continuity error, though there's no guarantee we, as viewers, will just overlook them.
