Numbered recommendation systems are missing some semantic meanings
Netflix asks me to rate a movie on a scale of 1-5. Where’s “I really wanted to like this movie, but it just dragged on and on” (Hero) or “I wasn’t in the right mood, but I could have liked it” (Hero), or “blah blah blah really pretty, but where’s the plot” (Hero), or even “it really sucked, but at least we got a good laugh – had I watched it alone, I might have clawed my eyes out” (King Arthur).
These indicate that I might like other movies in the same karass, but I feel bad giving them a high rating, because I didn’t actually like them.
