You know how everybody seems to like Big Bang Theory because it's filled with references to nerd/geek culture, but many of the jokes could be recycled into any setting? That's the vibe I get from this. Geeks seem to be a huge market these days, and most things that appeal to that market feel the same as things that are made to appeal to any market: They're here because they'll get attention and make money. That's it. Is there an artistic reason for this video? Something it is achieving that several other Katy Perry parodies haven't? Because I don't feel there is. I even like some things that do this (Big Bang Theory, for instance), but I can never shake the feeling that it's only been made because it knows it'll sell to my specific demographic.
