Most studios, for their theatrically released superhero fare, seem allergic to the notion of directly adapting the graphic novels/story arcs that are very successful in shining a light on the best aspects of these characters.
They just... don't do it. Pretty much refuse to, in fact.
Marvel's got their lane, obviously. Pretty much paved the whole freeway, really.
Fox has discovered their lane, which is the same lane Warners keeps trying to drunk drive into
Sony's decided to basically draft off Marvel's wake directly.
What are those three studios NOT doing that you can do and do well?
They're all not adapting their source material directly
They're all not aiming specifically at families
They're all not considering big-budget animation as a viable option.
Superhero films have been big business (some of the biggest, period) over the last 20 years and yet that lane is still completely unoccupied. (Sony's about to try it first, though)
Yet WB is going to continue trying to take some of the most iconic and inspirational stable of godlike superheroes (I don't mean the adjective godlike in the hyperbolically complimentary way it gets used here sometime, I mean literally deity-like) and swerving them drunkenly into Fox's lane and scraping all the paint against the guardrail.
Fox is doing what WB wants to do with their characters. Which makes WB's failure all the more pointed if they really are looking at Marvel and trying to replicate that. Because it means threw a fat dart at one target and wound up barely glancing off the board one over before quailing to the floor and sticking there.
