How do you decide netflix prize?

So, I just pound into the wild. I actually don't really know much about data. I ask out of sheer interest, because I really will not have time to try to participate in this competition.

But just for fun, how would you handle this?

It works something like this: you get a really large set of movie IDs and user votes. Now I got a few votes from a user and a film, what rating will he give in this film?

So, perhaps for those 3 readers who are NOT completely familiar with linear regression, like me: they demand to improve their forecasts by 10%. It's hard. This is difficult because I believe that rating a user’s choice is simply the average choice that other users gave is probably a good rating. I want to say that there is not much space left for improvement.
