There are two things you can't argue in film: comedy and eroticism. If something doesn't make you laugh, no one can tell you why it's funny, and it's difficult to reason someone out of an erection.
If there's anything I hate more than a stupid action comedy, it's an incompetent stupid action comedy. It's not so bad it's good. It's so bad it's nothing else but bad.
It is hard enough to be good at all, but to be good in comedy speaks for your character.
