Wow! so many thoughts running through my head!
First off, I'm a DC fan so you can suck it!! Just kidding, but I did grow up a DC fan, and primarily a fan of Superman - because I grew up watching those superman cartoons from the 50's (but I'm not THAT old).

Unfortunately, as much as I love superman, he is a TERRIBLE character to have in a movie, pretty much for the reason you laid out: he is virtually invincible. When Superman died in the last movie, I was really happy because I thought they had to get him out of the way for Aveng...I mean Justice League to work. But DC literally did the worst possible thing out of all possible options; here are the two options I was hoping for (other than keeping him dead): 1) He comes back, but as evil superman - they do their quick fight but he flies off not to be seen again in this movie, setting up the next movie with evil superman as the main "villian" they have to defeat/rescue. 2) Superman comes back as in the movie but he is still weak, and thus can't be invincible Superman to instantly save the day - that's too easy. But no, they had to take the easy, boring route of simply having Superman enter the scene to quickly save the day!!! Terrible!!

JL literally felt like a mashup of Snyder and Wheadon. I like both directors separately, but not together - the tone of their worlds just do not mesh, and I think we saw that in full force on this movie. The witty Wheadon quips don't work in the dark tones Snyder verse. I want one or the other.
This movie was so disappointing to me :(

Finally, I wholeheartedly disagree that Antman is better than Wonder Woman!! I'm on the fence about Antman vs Batman v Superman (extended cut) (have you seen the extended cut? I liked it a lot more); but I admit I'd probably give antman the nod in that one...maybe.

All in all, very good write up and I look forward to next thursday!!
