I've been surfing a while to help a friend build a little data base of movies and I've found this site:
www.filmaffinity.com
It has english and spanish versions (german available soon)
There you can rate and review every single f*cking film there is

At least I had no problems at all finding some argentinian films that I wrongly supposed would not be included in the database.....
You can add friends so you can check their ratings and reviews...and there are "movie soulmates" that are supposedly to share interests according to their votes and yours......
Check it out!!!
Warning!!! Beware of the compulsion of voting!!!
Oh btw...I'm listed
denaon over there too
