Once you can analyze all the things someone watches and all the views on a single video, then it's not particularly useful to know if this one person liked this one video. I'm not sure how much it matters how good each episode of a tv show is. Do you look up the rating of each subsequent episode before you watch it? If most people in your cohort were hooked enough for 5 episodes before tapering off, then certainly that's a tv show you may want to see. Also, if everyone was interested enough to sit through something even though most people would say the payoff sucked, as opposed to bailing on the video early on, then I'm not convinced it's much different from a movie that people sat through and particularly liked when it comes to recommendation. So people enjoyed 75/90min instead the full 90/90min, not very damning.
