I certainly can't say the first movie didn't serve up a lot of laughs or contained characters and situationss I can't relate to, but I really would love to see a movie about gaming that wasn't ultimately just an exercise in self-deprication and stereotyping, with the central theme being how lame gamers are (with the implication being that non-gamers are somehow less lame with the way live their normal and proper lives). It would be great to see some of the positives accentuated for once, so that a non-gamer could watch the movie and then say "I think I get the appeal now", rather than affirm their prejudices.
Basically, celebrate the hobby while roasting it.
