Legend
The humour is superficial, though - the underlying and important bit is that he understands heart and heroism and doing the right thing and caring about others, despite conflicts you might have with them. That's very clear from GotG, TSS and Peacemaker.Gunn made a few good Guardians movie, and Suicide Squad was a riot. Neither of those are Superman, though, and I do not want a Superman movie that is full of the flavor of humor from either of those.
Take away or reduce the humour and you've got some extremely heartfelt and earnest movies, frankly. And indeed large parts of them are just that! Especially GotG 2 and 3. This is a man who managed to make Rocket Racoon into a compelling and sympathetic character, for goodness' sake!
It's obvious from what has been shown and said about the movie already that Gunn isn't going to have Supes cursing like a sailor or flipping off Green Lantern or something. It's already evident he understands Supes far better than Snyder/Goyer ever did, which was always a very superficial thing, where they were confused by heroism, and only really understood that Superman was powerful.
