Eberron is kind of all over the place, as a campaign setting. And I know that is the entire point: Kevin wanted to create a world that could support every possible kind of game theme that players could want: grimdark fantasy, gothic horror, heroic epic, gritty war, magic school, high fantasy, airships and wizards and dragons and robots and vampires and zombie pirate ninjas on dinosaurs...if you could imagine it, there was a place in Eberron that you could place it and it would make sense. It's the key strength of that setting.
Unfortunately, that's precisely why I don't think it would work as a TV show setting. The writers/producers can't capture the entirety of that campaign setting, with all of its different themes and flavors, into a single TV show and still have it resemble Eberron without it getting muddled beyond comprehension. It would be amazing if they could pull it off but it would be a very hard sell to any production studio....that's a lot of stuff to cram into that single pilot episode. Just to get it green-lit they would have to narrow it quite a bit, and that's the opposite of what Eberron is to me.
