I'm a 20 year old male and was roped in to seeing this with my girlfriend, and I'm glad for it. The film has an incredibly predictable storyline, the acting isn't great, most of it complete and utter non-sense and most of events in the film hold little to no purpose.
I've gave it a high rating, however, because I don't think I've laughed quite as much at a film as I have at this one for a long, long time. I think the phrase 'so genius it's bordering on madness' applies here: the film isn't good, but that's where it succeeds. It's one of those films that aren't meant to be taken seriously, and as such you can just relax, and have a laugh. I spent a good hour or so crying of laughter, and I could't even catch my breath during the "I'm Spartacus" motif in the 'Honour Court' -- unintended comedy genius.
While it's no Space Odyssey and has less character depth in the entire film than is seen in one minute of A Clockwork Orange, it is nevertheless worth the watch.
