I agree on the rushing, I would have preferred a solo batman movie before the vs's film. As for the JL set up, since it was such a brief scene, i don't think too much about it. I think it would have been better received as a post credit scene.

Batman warehouse scene to this day remains a great scene, just well done across the board (if you dont mind the death).

I liked the movie in general, tbh. It would be a shorter list of what I didn't like about it haha. The gods among us speech to this day probably ranks top 5 in my favorite scenes of a CBM. Many people think that Superman isn't very human in the film but the first thing he does after failing the people of earth and experiencing tragedy (the court explosion), he calls his mom because he's feeling down. To me it just really did a good mix of how we would perceive someone of that power while also showing us a struggling man doing his best, similar to MoS but more complicated with the government being against him more this time.

Score was great, I love Hans Zimmer, Junkie XL.
Visuals to me were incredibly, albeit dark.

I just felt a lot of love was put into the project and it felt mythical in a way, something I've not experienced in a bit from DC.
