Dahmer, also known as Monster: The Jeffrey Dahmer Story, is expected to be one of Netflix's most popular programs of the year. It's the most watched series debut since Stranger Things season 4 earlier this year, and it's already the top show on the service in dozens of nations.
However, given how the real-life serial killer is portrayed in the show, Netflix keeps encountering disputes after disputes. If you've seen the show, I don't think it's possible to claim that it 'glorifies' Dahmer in any manner, but the problems with it originate from how Netflix has characterized it and the fact that it was produced in the first place.
