I've just imported 300+ ratings from IMDb into Criticker, and the recommendations it gave me seemed so far off that I didn't even feel like giving any of the movies a chance. Maybe I'm not watching enough classics, but it feels like the site hasn't really gotten to the long tail of movies.

In comparison, when I go rate movies on IDMb I'm rarely more than one star away from the average rating, so IMDb serves my needs quite well, anyway.
