I suspect this will be one of the most controversial films in the MCU. We will do our best to avoid spoilers but there is one element that is revealed in the first ten minutes that is unavoidable if we are to have an intelligent discussion of the flaws of this film. If you have to wait until you see the movie to discover the villain, then you have not seen a trailer and you should stop reading now and come back next week after you have seen the movie.
This second film in the Doctor Strange centric universe does some damage to the story arc of a major character who has been an Avenger and the subject of their own Disney Plus spinoff show. It may be a plot thread that is consistent with the comic books that the character originated in, but it is a complete reversal of the character's journey in the steaming television series.Wanda Maximoff is a character that we have suffered with and who managed her grief , ultimately learning to live with it in a mature manner after the events of "WandaVision". This movie throws out most of the character development of that show and it keeps only the concept of the children that Wanda invented. Somehow, the Scarlet Witch takes over and becomes obsessed with a problem that Wanda has already managed. This makes Wanda the major antagonist of the film, and for people who feel her pain and the steps she has gone through up to this point, it feels like a betrayal.
Writer Michael Waldron, who did a terrific job with the "Hawkeye" series, has fumbled the ball with this film and some of the lazy writing is evident in the most obvious of places. Taking a character who can manufacture a world that Doctor Strange feels is "so real", make the most annoying slip possible to accidentally reveal her intentions is the most basic example of that laziness. Later in the story, the wisest beings in one of the multiverse worlds, are completely blind to the threat that the Scarlet Witch presents, which makes what happens satisfying in a way that is also cheap. Wanda's character is also so focused on the selfish goal that she is pursuing, she ignores all of the sacrifice made by others, including her lost love, and it is as if the grieving process never took place at all. Her inability to look at reason, and to think that the absence of killing everyone is a measured choice, just seems silly.
Having said this, I still want to say I enjoyed the film for what it is on it's own, rather than for it's place in the extended MCU. Doctor Strange and Wanda are like a different version of magical wizards Harry Potter and Voldemort. They cast spells at one another, they find ways to trick each other to gain the upper hand, and it is always about the fact that it has to be these two characters who face off. Replace wands with the fling rings and magic shields, and you get the picture. They even stage a sequence that will remind you of the battle of Hogwarts. That is not a bad thing, but it is derivative and another example of the lazy writing. Regardless of those points, I did like the last act, and even though you can see the resolution coming, it still works.
Director Sam Rami was chosen for this project for a pretty obvious reason, that final act. You could easily think you had stumbled onto the sequel to "Army of Darkness". The Doctor Strange in the final showdown is an extended version of a comic book character that Rami created for his 1990 film, and it is just as cool as an outake from "The Evil Dead". There are deadites but there is no chain saw. In the one consistency in telling the story, there is a consequence to using the "Book of the Dead", I'm sorry, the "Darkhold", but you do have to wait for the final moment of the main film to see it.
There are spectacular visuals everywhere you look. In visiting some of the other Universes, we get clever twists on our own world, and there are nods to some of the elements of the comic book cosmos as well. Blink and you might miss a reference to another Multiverse Marvel film that will be coming out later this year. I think red means go is another lazy plot transition, but it does justify some of the actions that Steven Strange commits in that world. The actors are all good, although Michael Stuhlbarg is even more wasted as a presence than he was in the origin story. Elizabeth Olsen gets a wide range of deviousness to play, Benedict Wong continues to be an MVP in the films he is in, and Rachel McAdams does have something to do in the film, but I can't say too much. There is a fun piece of fan service with the Illuminati, serving as a alternative universe set of Avengers, and I was was surprised by the characters and cast and would not dream of saying more.
So having dissed the storytelling and praised the technical accomplishments, let me say that some people will enjoy the heck out of the movie, I know I did, but not for the reasons you might want to enjoy the movie for. I did not see the Delta 33 but I'm sure it was there. I did however see his other trademark and enjoyed it immensely. Rami fans will know what I mean, and you want to stick around for the end of the credits to get the final stinger.
