I preferred the 5 star system. But then youtube, facebook, wikipedia... all major sites eventually stop caring about what the users want and just sit back and watch as users then try to navigate round there website. Fortunetly I got used to facebook (until the next update which noone wants or the privacy settings change, get reverted, change back then settle into a happy medium), I signed up for a wiki account purely to be able to have the old setup back and well, youtubes for watching videos, I dont care too much about rating them.
In other words, this topics pointless and Im changing it into how all sites are becoming less user friendly. (except ms, of course)
