At first I was mad and I was also like you saying some dramas don't deserve this much rating because it was bad for me. But like Kate said, if you've been using this website for awhile, you should know that the ratings aren't so great. I used to depend on ratings too and ignore some really good shows, so just don't depend on ratings or question about it. This is not new also, this problem is with every show on MDL.
Same! What I've found is that many on MDL like things that I just don't like, so I take ratings with a grain of salt. i.e. Everyone raves about My Love From the Stars, I HATED it. And others that I've enjoyed, people have given low ratings.
