A clumsy, ugly, disappointing mess

Rating: 4/10 (11 March 2019)

(This review will have major spoilers.)
To start out with, Gal Gadot looks the part of a goddess very well, but her performance is mediocre at best. Chris Pine is serviceable with a few decent scenes. The only actually good performance is from Saïd Taghmaoui, who plays Sameer. His character does basically nothing, like all the secondary characters in this film, but he was at least entertaining to watch. There is sadly not a single character arc in this film, not even from the title character, which was disappointing to say the least.
The fish-out-water scenes in the middle of the movie are decent and have most of the good lines of the movie. Aside from that though, almost nothing here works. From the exposition dump across the first half-hour, to the badly-shot fight scenes, and the ugly Zach Snyder-style cinematography, nearly every aspect of this film is incompetent.
I could list of innumerable poor decisions here, but to me the most egregious error the film makes is its second ending. (If you care, this is the spoiler-heavy section.) Ostensibly, the first ending of the film is when Diana kills the man she believes to be Aries and then the war continues unabated. For a moment, I thought she was going to be forced to learn a lesson about how she was wrong, and you can't kill just one person to stop a war. This would be a solid payoff to the naivety that had been thoroughly established up to this point, thus completing her arc. But alas, this is not what happens. Instead, she discovers the real Aries and proceeds to have a giant CGI-heavy fight with Aries that looks truly horrendous. Defeating Aries here stops the war, which means Diana was right all along and thus learned nothing. But she also defeated him in the most disgusting final fight I've ever witnessed. That ~20 min fight at the end brought the rating down 1 star, on its own.
I loved the first film Patty Jenkins directed, Monster; I view that as a near masterpiece. But here Jenkins has directed Wonder Woman as a character with no arc surrounded by other characters who also have no arc and who have essentially no impact on the plot. Wonder Woman learns nothing and gets into a lot of ugly-looking fights along the way. Her relationship with Steve Trevor (Chris Pine) is rather cute and she has a handful of funny lines with him, but sadly that's the only bits of value this film has to offer.
