The review embargo lifted a few days ago, it has
84% on Rotten Tomatoes and a
70 on Metacritic. Seems to be your standard MCU film. They're praising the performances of the main four and saying the third act is underwhelming, the villain is weak, and the apparent need for every MCU movie to end with a big CGI fight kinda brings it down a little but it's still pretty enjoyable. I've seen things that suggest the recent leak about
Taskmaster being Dreykov's daughter was real so I'll give them props for that, they actually changed things up. I'm not a big fan of how it's apparently more Yelena's movie than Natasha's but idk maybe it works well and just sounds bad on paper.
Also I was looking at stills and I noticed that Red Guardian has "KARL MARX" tattooed on his knuckles. This isn't really an issue, I just think the whole Russia=Communism stereotype is kind of tacky but I don't know what I was expecting from a Marvel movie.
