I recognise all three of the points you make, Fred. That being said, networks have been able to produce something halfway decent in terms of ongoing plot (Lost springs to mind, but even Agents of Shield manages it on a major network).
While I do dig the blood and gore on Daredevil, network shows like Buffy, Shield, and a bunch of others have managed to be less camp than the writers of Gotham seem to want to be. And it's not like Gotham is all PG happiness - Fish Mooney dug her freaking eye out :lol:
It's shitty writing that holds Gotham back. It could be a huge show given the number of homes it beams into.
