Mother of all "jump the shark" endings

Rating: 1/10 (2 May 2018)

There is no way back from this without some galactic undo button. If I wanted alternate timeline crap I'd be watching those sad Star Trek redoes.
The premise is lamer than Civil War (which was heroes can't save everyone so government regulation to the rescue). Some idiot thinks because his world collapsed that either a) ALL civilizations will collapse in similar fashion and/or b) that galactic genocide solves the problem.
I have left movies melancholy, brokenhearted, and terrified. I realize not all stories have a happy ending, but I've never left a movie ANGRY until now.
Seriously Marvel...screw you.
