Re: The thing is..
> Wether or not Fanboys is crap has no effect on the definition of cult movie , so Dave is correct to say "That almost sounds like a textbook definition of 'cult classic!' ",
True - I should have maybe clarified that the /audience/ Rotten Tomato reviews generally damn it with faint praise, but I'd already typed more paragraphs than can perhaps be justified in a lunch break, and I'm sure someone would point out that negative audience reviews are also common for cult movies ;)
Either way, perhaps the greatest criteria for a cult movie is that people care for it, and in Fanboys case, that doesn't seem to be the case: people watch it, comment that "it's alright if you're a Star Wars fan" and move on.
Anyhow, that's enough elitist ranting for one day!
