Amazon Recommendation Crack Machine

Amazon.com seems to think that the only thing I ever watch is Doctor Who. My first page of DVD recommendations is almost exclusively Who (and Pixar's Cars for some reason).

*checks why* Oh, that would do it. I forgot that I buy most of my Classic Who off of Amazon. And I own the entire Key to Time series (what? Tom Baker is made of awesome).

I need to add my Who to my DVD Database at some point.
