One thing that a handful of studio development executives and some very hardcore Marvel fanboys have in common these days is an adamant belief that a "shared universe" is the only way to go with adapting certain material. The success of the Marvel Cinematic Universe has certainly lent weight to the argument, but in its case it had decades of comic book source material, years of planning and plenty of careful world building across individual works before fully unveiling its wider ambitions. Others who're attempting to jump on the bandwagon don't seem to be anywhere near as organised or patient with the process.
