There is no doubt, Vince Gilligan is now the best showrunner in the business.
Definitely top 5.
Which actually feeds into the problem the networks have. They don’t let show runners run their shows. Networks constantly micromanage their shows. The word I’ve seen from everybody on AMC is they get the standards and practices book and their budget and pretty much get left alone after that. The networks are so terrified of making mistakes they constantly make mistakes, AMC (and the other good networks) assume their show runners are professionals and let them earn their pay.
