It would be really cool if the top 50 or top 100 would use peoples ratings 1 to 10 to help calculate where it belonged in the ratings and not just votes.
Some drama's get a lot of votes but have many people who rated it 4 or 5 or sometimes less. Kimi wa Petto would be a good example. a lot of people did not like it but it is highly ranked based on number of votes it got. If they did an average of votes it would likely sink in the ratings. Some great drama's have all 9's and 10's by everyone who saw them and are not even in the top 50.
