What genre do Marvel films belong to?
If well written they dipped into every genre. I remember one time when "Noir" was a thing for a year or two. Specifically Spiderman noir, X-Men noir and one other were mind blowing. Depends but mind blowing.
Emma Frost & Cyclops didn't even really change. Turns out they've been noir the whole time. And really if you follow the next decade based off the limited series it plays out to be the ultimate noir with the Emma Frost using Cyclops corpse to further his goals. Now that's fucking love, but in the darkest way possible. People feel like she's gone back to being evil. But I see it as a wife going the whole nine yards in loving memory. It's just so damn grim!
