I beg to differ What about a post Ironman movie based series having Tony combat not only armored foes,but business rivals that try ruin Stark Industries it could lead into a Live action Avengers series as spin off. Cameos by Sam Jackson as Nick Fury.
I could get into an X Men prequel series showing formation of the School for gifted children to how did Professor X get into his famous wheelchair.
Yes I did watch Wolverine X Men Origins on demand,and saw Professor X standing on his two feet.
As to a real network ,running a series like the Marvel live action ones SyFy comes to mind. DC will stick, with CW because of the current track record with Smallville.
Thats my two cents
