Content-based data may not help with Netflix prize, but they do help to quickly drill down to what people want to see. You can pick a "nano category" based on the meaning of the words in it, rating data can be superior but cannot be used interactively in such a manner. I've thought of doing a service like this movie search engine, maybe I still will. Search engines don't really leverage interactivity as much as they should. Consider a simple example: I choose Pi as a movie I like and Drama genre and get a search box to search within dramas similar to Pi. Providing context can go a long way towards getting what the user wants.
