What's so special about air guitar?
I don't think that watching some dude play air guitar is very entertaining at all. In fact, I was so bored with it that I couldn't even watch the entire thing. Air guitar isn't even hard to do... Why document something that is simple? Hey look everyone... I can move my hand up and down with the rythm of this song! It just isn't interesting enough to show people...
Maybe if the guy was playing a guitar solo, it might have actually been challenging... But no, the guy was just strumming. Strumming is the easiest technique you can possibly use while playing a guitar...
In conclusion, not only was this boring because it was a film of some dude playing air guitar, but it was especially boring because he was strumming along to it...
