Even though CW was a blockbuster comics event it would be impossible to make an accessible CW film.
First and foremost, there are not enough superheroes with secret identities in tbe Marvel Cinematic Universe to warrant an across the board registration. Nowhere in any of the Marvel Studios releases have there ever even been the mention of a mutant, let alone Spiderman or any potential vigilante threats.
That said, I love the dynamic between Cap and Iron Man. I hope that in the future their personal differences continue to be expanded on while ultimately their heroic similarities continue to kick the big bad's ass.
