You're not the droid they're looking for. Since Netflix gave $1 million to random people for improving their recommendation engine a bit, I'd say there's a lot of value to be created here.

It never hurts to think bigger, too. If they do somehow achieve a big advance in selecting movies, it could probably be applied to books and movies too, right?

It's hard to think of a more impactful problem for the entire entertainment industry than better matching of products to consumers.
