i'm not entirely in agreement here. one man's junk is another man's treasure etc and therefore a not-so popular show may be liked by others just the same as a popular show doesn't have to be liked by everyone.
the votes should balance out the more people vote, so if anything i'd say the problem lies there..more people need to be voting on the shows they follow.
The only effective method to deal with hate voters would be to somehow encourage more people to vote, to compensate. But demanding from people to explain their votes it's not really fair nor effective.
I checked out the user who gave the "1" votes on Jessica Jones. It's a somewhat odd behavior, but I don't think it's malicious intent: he/she has hundreds of votes and 90% of them are either a 1 or a 10.
I don't know if there's anything to do here, apart from encouraging users to vote more frequently. We (and every other site in the world with ratings) offer the option to give a rating of 1, so we can't complain if someone uses it. If a user only ever votes 1 (or 10) it would be cause for concern, but otherwise probably not.
