While not exactly what you're looking for, I find myself going back to http://nanocrowd.com quite often for movie recommendations.
They don't do TV shows, but their niche categories are usually pretty solid.
It works well if you can give them an example of the type of movie you feel like watching. For instance, I wanted to watch a cheesy, nerdy, thriller earlier tonight, something along the lines of Hackers and it suggested The Net, Antitrust, TRON, Live Free or Die Hard, The Matrix, Swordfish, etc. Exactly what I was in the mood for.
