I have to say that I was also a bit disappointed with Monster Camp because it wasn’t the most positive movie about larp'ing at all. I haven't seen Darkon but if it also only focused on the nerds and less successful people that’s too bad.
However I can understand that some of the more normal people who play these games requested not to be in the movie. I have a large group of friends at St. Olaf where we go to college and we play larp pretty much all day every Saturday on campus. (There are nice woods right outside one of the dorms that we use.) There is a large amount of nasty feelings, resentment, and cat calling that people direct towards us for really no other reason than we do something different. I know for a fact that some of the newer players didn't even initially tell their friends they played larp because they were afraid of being snubbed for it. And I've had people yell random curses (not the spell type) and swear at me from passing cars as I walked around in my costume. It is immature and sad.
It is a ridiculous and totally intolerant attitude, completely opposite what the "normal" educated people profess how they think. The fact is that people have problems accepting something that they don't understand or don't know about. And often larp'ers makes people feel uncomfortable. For many people tolerance boils down to "when I feel comfortable" this is very unfortunate. And also the age old "I feel better if I chop other people down" doesn't end when you get out of High school.
I'd love to see a movie made about Alliance larp which had some interviews with people who do have regular successful lives and portrays larp'ing in a good light. For me it gets me out of MMO's which I have a tendency to get totally addicted too and are not good for me, so in that way it’s a cure for me. Its also active, stimulates creativity, interactive and not something you can do for 23 hours a day even if you tried (because you need other people). I hope that maybe sometime in the future it will be accepted just as another reasonable hobby that people can play and not be discriminated against for doing.
