Hardly matters either way.

First off none of these superhero movies can have consequences. In the long run the stories are always rebooted, and now that they are multiversal the only inherent meaning must be completely nihilistic.

Scone, In a multiverse no choice matters at all. Especially once the characters in that multiverse are aware of it. It just introduces a paradox into any decision the characters make (ad infinitum). It's worse than time travel as a plot device.

Also it doesn't matter because you may be right. Possibly audiences are getting smart to superhero movies without consequence and maybe that's why it failed.

Or audiences were generally not sophisticated enough to appreciate it, and it failed.

Or Zack Snyder packed too much meaning into a comic book movie, and it failed.

In the end, it failed. MOS suffered a drastic first weekend drop in ticket sales and this is Zack Snyder's responsibility.

He failed, it's over, and I'm glad. We are about to see how much damage was done to Superman's Legacy.
