I don't agree with super-delegates either, but again, Sanders goes into this knowing the rules. It's not right to then act like you were wronged because what you knew would happen happened. And by the way, Sanders was hoping for a contested convention in 2016. And there is a reason that a contested convention exists. If there are a ton of candidates and one wins simply because they got more than the others, but still is significantly short of a majority, they don't necessarily represent the will of the people, they just won because their opponents were too divided. I don't think superdelegates are the answer though. The answer is ranked-choice voting.
