Most of everything sucks. The point is that the showrunner model, with rotating directors and writers, is the industry norm; it's not some goofy thing Amazon is doing to cut costs.

I saw the first season of American Gods on Starz as well. It did not motivate me to watch the second season. That same year, though, we had The Good Place (showrunner), Better Call Saul (showrunner), The Deuce (showrunner), The Leftovers (showrunner), Maisel (showrunner), and Legion (showrunner). I think the model acquits itself nicely.
