I might be crazy but I really really cannot take a machinima that plays it straight serious. Maybe I'm just biased because I used to make crappy machinima videos as a kid with my friends, but there's just something so jarring about seeing a story being told in a game engine that asks me to give a damn.
I don't want to minimize the work that people put into their shows either. I've seen some works come out of the machinima community that on purely a technical level are quite impressive. I have a few friends I've made through online message boards that gave me serious voice over roles in their shows back when I was in high school, so mad respect. Am I the only one, who is not an outsider to machinima, that feels this way?
