I've watched the original in University with the old black and white tapes. There have been interviews with people years later who said, "I really believe I killed that person in the other room," and furthermore, it has been replicated in other countries by other researchers.
We can argue about numbers and percentages, but the idea that you can put up walls of abstraction to get people to kill others is established in other research outside of Milgram.
Even if there were problems with the original experiment (and I've read Dimow before and doubt what he's saying; there are interviews from former participants who said they really did believe they had killed the person in the other room), it's been replicated in other countries.
Today, it's unethical to preform the Milgram experiment. Michael/vSauce did preform the actual trolley experiment for a YouTube video, which is interesting, but it was bad scientifically because the sample size was too small, the experiment changed for one person, and the ethics for the entire thing was questionable.
