It's astonishing that Marvel has put on what is effectively a 10-year master class in action movies in general and superhero movies in particular, and Warner Brothers hasn't learned a thing. There is simply no aspect of this movie that exceeds the mediocre. The plot is pure formula, without the slightest twist to provide any interest. With the exception of a single Gal Gadot scene, the acting is mailed in. I take that back, Pedro Pascal, who played the villain, at least put in the effort to ludicrously overact. It is too long, too repetitive, and too expository. Even the special effects look amateurish. Honestly, given the state of technology it seems you would have to try very hard to produce outright bad special effects, but they managed. The cinematography is prosaic. The dialog is juvenile and dull. I only hope there was a PA or a Grip or someone who did something worth doing in this mess.
Strangely, it has an oddly poignant moral about accepting the truth even if it is painful, and understanding how your best desires can lead to disaster. A good theme done disservice.
Warner made a big deal about streaming new releases on HBO Max. HBO may regret that deal if this is the sort of thing they can expect.
