Amazon has a section where they recommend items based on your previous purchases. They recommended "Smallville: The Complete Ninth Season" for me even though I have said that I was not interested in any of Seasons 1-8. They recommended "George Lopez - The Complete First and Second Seasons" because I bought various Gilmore Girls seasons, however, Gilmore Girls is a comedy/drama that was very well done with mature humor whereas, Lopez is slapstick.
"Jack the Ripper" because of "You Only Live Twice"(James Bond) is there any connection that normal people can find? "Alien Nation - The Complete Series" because of "Greatest American Hero"? "The Complete UFO Megaset" because of "Our Man Flint"? "Mannequin & Mannequin 2: On the Move" because of "Due South"? "Grey's Anatomy: The Complete Seasons 1-5" even though I told them I wasn't interested in seasons 1 or 2 or 3 or 4 or 5!
I also like there search engine. I was searching for "Swedish Music" and the "Dumb and Dumber" DVD came up as one of the items. Searching for "Castle Season 2" bought up "Married with Children - The Complete Fifth Season" (not seasons 1 or 2 or 3 or 4 but 5) in the first page.
Of course, some of the recommendations make sense and the search comes up with the items you may like most of the time.
