I'm not sure I would peg all of the Marvel movies as action-COMEDIES. I mean, for every Guardians and Ragnorock we have Civil War and Endgame.
The best thing about the new cut of Justice League is that the story opened up enough to give some of the characters room to breath, and that gave JL more of a "heart" than it had previously.
Despite Zach's best efforts to quench it by draining the film of every last spot of color. In a related note, I have no need to see the B&W "gray" version of the film.
I've already seen it.
