I would now start with the unpopular opinion that Breaking Bad is actually slow, I've tried to watch it 2 times, both ending on not finishing the first season.
I also don't understand how Mad Men is a thing. And I work in the advertising field for like 10 years. Also, I find Jon Hamm and Elizabeth Moss as impressive actors. Still think this show is 'meh' at best.
