Ask HN: What's the best movie recommendation system?

I was getting tired of searching imdb top lists and checking review sites for movie titles.I wanted something with a good intuitive recommendation system .

The first site I came upon was http://www.icheckmovies.com/ I checked about 300 movies + likes and dislikes and got 2 recommendations I was dissatisfied with.Deleted the account.

Right now I'm rating movies on movielens. What are you using ? Any recommendations ? Thank You.
