No, as far as I know the ratings come from Rotten Tomatoes in some way. However I'm not sure how they get converted into a star rating. I like RT's percent ratings, and the fact they separate out critics from users (same with IMDB) and would much rather see those displayed rather than the star rating - presumably a 2 star rating could be anything from 21% (unlikely to bother with) to 40% (worth a shot if it interests).
Of course you have to make your own mind up at the end of the day but with so many movies to choose from on the cinema pass a good rating system does help (and Netflix have some pretty sophisticated recommendation algorithms going on behind the scenes ehich makes their ability to rate movies yourself worth doing).
