The argument that the movie made look like Billy Mitchell look like a asshole is bullshit, a few years ago he was on MTV True Life: I'm a Gamer and he was a asshole in that.

The movie is totally legit, the filmmakers went out to make a movie profiling a lot of the classic video game players(Billy, the old lady, the Mappy Guy and so on) but stumbled into the whole Donkey Kong thing and went with it.
