I was a little surprised I liked this movie as much as I did. It's a solid three stars: I was entertained for a couple hours, didn't fall asleep much, and don't think I would have regretted not seeing it.
Let me tell you, though: Gal Gadot probably added a star all by herself.
So at the end of the last movie, Superman was "dead". And the world is menaced, as worlds are, by Steppenwolf, who's looking to put together three powerful cubes of alien technology, and employs a lot of nasty flying monkeys to assist.
Batman is the first to notice the problem, realizes he doesn't have much of a chance to thwart this scheme on his own. So he recruits all the other superpeople he knows about: Wonder Woman, Aquaman, the Flash, and a new guy "Cyborg", of whom I was previously unaware.
Still not good enough. But if you think Superman is going to stay dead, … well, of course not. We all know better.
