I've had the pleasure of watching the crapfest that is undefeatable. That movie was so bad it defies any logic, and yet had the best showcase of mullet fu I've ever seen on film.

It's a shame they missed this one though from code of the dragon:

There's rubbish, and then there's stupid. The horrible martial arts movies cited by totalfilm.com are, as they say, total rubbish.

Stupid exists for its own sake, which elevates even beyond the intent of the story itself.

For my money, the awesomest of awesomely stupid fight scenes is Inspector Clouseau vs. Cato in The Pink Panther Strikes Again.
