This movie does everything a B-movie needs to do, to get your attention. It's pretty trashy, it's pretty out there (who cares about historical accuracy anyway, right? ;o) ) and it does have some extreme ideas and still some decent acting (all judged by the limitations of budget of course, don't compare it to a blockbuster). If that sounds intriguing to you, than do not mind the silly name of the movie (though maybe the silly name prepares you somewhat), but do watch the movie and just enjoy it as it is meant to be.
Having said that, if you can't fathom the idea of mistakes, ridiculous behaviour, OTT acting or OTT special effects at times, plus some explicit scenes of violence, than you might want to stay clear of this. It is not a great movie by any sense, but it will entertain you, if you let it.
