It's not a great and definitely it's not bad either, it is a "pretty okay" movie.
Actors are great. It's given that Gal Gadot is perfect for the role. Pascal and Wiig did a great job with their characters. And I really like how they portray and turn Barbara into a comic-based Cheetah and not just a normal-looking girl with powers.
Film score is good. Visual effects is kinda off on some scenes but it's good and appealing most of the time.
The narrative is a little bit cheesy. It starts good but it became less interesting later. The fight scenes are well executed but it needs more of that. The message is relevant but the ending missed its mark.
Overall, it's a good movie but it's not as good as the first one.
