How bad is it? It's the second worst wrestling twin brothers film (yes, I have another to review).
Should you see it? Go ahead. You've seen worse.
Two orphans are raised by traveling entertainers. An evil ruler wants a girl for his harem, so the twins become gladiators and have to fight a dragon (this makes sense eventually, if you watch the film) to make things right. This is one of the silliest swords and sandals barbarian films and has some intentional laughs and some decent action.
