I think they shouldn't mix the films and the shows. Keep the shows separate from the films. Honestly, if theirs a thing they get right it's the shows. These days they cant make a film about heroes to save their life. Hell, the only successful film series was Nolans verse of batman. And key word, Nolans verse. (As in he doesn't really fallow the comics, he did his own thing. Successfully so. Making it his own verse all together. Like an elsworld story.) I think the tv shows are where attention should go. If they just keep it up, they can have their heavy loyal tv fan base watching the different tv shows while they rack in profits from adds. The shows can be their rival to Marvel/disneys movies. Instead of playing catch up, and trying to connect a tv show to their current movies. They should try and continue their own path. Lets face it, disney won the movie market. If they dont play smart, and continue with Arrow, Flash, Gotham, and further spin offs? They will fail and lose the tv market as well. To shows like Agents of Shield, and dont think Agents is the only show planned. I bet you Disney is thinking along the lines of "Hmmm... Well, we dont own Spiderman in the theaters, that goes to Sony. But we do in cartoons... Oh! Let's make a spidey tv show!"
Like corporate bafoons often do, Fox looks for the easy profit. The path of least resistance. They look at how other people are making gross sums of money and thinking, I need to do that to! Instead of thinking, how do I one up that? Or How do I do something new, that people like as much?
