This was just a knock-off Bourne or James Bond movie, with the Black Widow and her family of spies as the stars. The action scenes in the dark rooms were really bad, because all the characters are dressed in similar black uniforms, so I had no idea who was doing what most of the time. I guess this was all CGI? It was impossible to follow.
Black Widow is not very interesting, and most of the best lines come from her sister (Florence Pugh), and her father, the Red Guardian (David Harbour). The comic book version of Red Guardian was totally tough super-soldier, but in the movie he is just a fat has-been, like Thor in the last Avengers Endgame movie. Harbour is mostly around for comedy, but he is a good actor, and makes his role interesting.
Rachel Weisz plays the Black Widow's mother, and it is a pretty generic performance. The story is really odd, as Weisz is the brains of the Russian spy system but she is on a farm doing brain control experiments on pigs.
The main Russian spy master was a very generic Russian character talking about world domination and power. He could have been from SPECTRE. The guy reminded me of Blofeld, and several other SPECTRE leaders from past James Bond movies.
TaskMaster was a very unique and interesting character in the comic books, and he is totally destroyed as a character in this movie. His entire back-story, character, and everything about TaskMaster is changed, and not for the better.
This movie takes place after Captain America: Civil War, and before the Avengers versus Thanos movies. It seems like this movie should have been done and released about five years ago, and it is out of place in the current Marvel Timeline.
