I still have a lot of music-savvy friends who deny the validity of the the name Genius for Apple’s recently implemented iTunes music recommendation engine, but regardless of how appropriate the name may be, the service has now been turned on for movies and TV, too. That means selecting any movie or TV show in your library should bring up Genius recommendations in the sidebar, so long as you have it turned on and are using iTunes 8.1.
Genius results are about as accurate as you might expect based on your experience with its usage regarding music. The top results are always episodes from the same series and season as the content from your library. When I tested it out using “Battlestar Galactica,” Season 1, recommendations from beyond the series were fairly accurate, at least getting the genre right, and included “Terminator: The Sarah Connor Chronicles” and “Firefly” among the top results. A similar test with “Heroes,” a far more mainstream program, brought back bizarre results, with the top recommendation outside of the series itself being Dexter. Only parallel I can draw between the two is that Dexter is a serial killer and Sylar is sort of one too. And both star hot girls, maybe?
You also get a new TV Shows tab in the Genius: Just for You subsection of the iTunes store main page. As you can tell from the screenshot from my own recommendations, I am indeed a huge nerd, and aside from Supernatural, iTunes knows me all too well. I suppose it would have shown me Movies recommendations as well, but I don’t actually own any iTunes-purchased movies as of yet. Let us know in the comments how well those recommendations are working out.
