Should Marvel use the darker tone employed by Fox for the X-Men in the Marvel Universe? Or should they adopt the somewhat playful tone they use with the Avengers?
I thought Fox went too dark too much. Their X-Men were mopey and generally lacked humor, save for Wolverine (sometimes) and Deadpool (always). This approach would also limit the X-Men's appeal. I'm not totally against a dark tone if the writing is good. God, please let the writing be good.
I'd like to see the tone set about halfway between the MCU Avengers and the Fox films. There should definitely be times when characters enjoy themselves, especially if the cast involves any amount of teenagers discovering they have superpowers (like Spider-Man).
