Netflix Spotter

Here's a great new feature for netflix to add: A netflix user spotter who watches customers for movies they would most certainly hate and warn them before renting it. I don't think it'd be that hard to look at a user's past renting history and see that this movie is outside their normal movie realm. I imagine the notification would go something like this: "Hi Grant, I see you're trying to rent Across the Universe. Perhaps you didn't see that this is actually a musical that bastardizes the entire Beatles catalog into a lengthy, boring and poorly made movie. Would you still like to take the time to rent this?" To which I would respond: "No, I don't want to rent that anymore! Thanks, Netflix, for letting me know!"
