I don't agree at all. I want to be able to rate an app that made it impossible to sign up with 1 star. Or that required access to my camera even though the app has nothing to do with taking photos or images. So, no time in but the app deserves IMO 1 star and potential customers should be notified to stay far away from the app

As for breaking apart reviews into categories that also has its problem. Zagat used to rate restaurants in 5 categories and it ended up requiring people to lie if they wanted to convey the message "do not go here".
