People still aren't going to watch what they don't want to watch. Simplifying the voting does not encourage more people to watch crap shows. For me, it actually makes me not want to give some shows I've never heard of a chance even if it is highly rated because I do not trust the rating at all.
One of the main reasons I started using Netflix was because the rating system could introduce me to shows I've never seen before that I enjoyed, and the suggested rating was almost always spot on, and, if not, at least I felt it would make my ratings more accurate when I gave it a lower rating. It was customizable. This new system is NOT customizable and feels very much like I'm giving into someone else's agenda rather than my own, not something I want out of a "service."
I've debated to stop using Netflix over it, but there is not a good competitor with a similar system and database of media with a rating system like their original. Hulu may be the closest, but it is very hard to rate titles there since the apps do not have full functionality.
