Another Netflix annoyance: if I watch the pilot episode of a series, then weeks and months pass, and I never watch another episode of that series, it's probably safe to infer that I didn't like it and you can stop recommending stuff to me based on my "interest" in that series. I feel like there's a few of these really common-sense things that Netflix doesn't pick up on and probably don't require some fancypants algorithm to detect.
