Review systems need "page rank" or at least some way to filter based on whether you, personally, found a review helpful.

I don't care if a 10 year old rated an app 1 star because they didn't like the colors, or a new computer user was confused by an interface. I want to know if people like me -- with my experience level -- found the app difficult.

Movie reviews follow the same thing, it's hard to look at overall ratings. I want to know the opinions of people like me.
