Doctor Strange in the Multiverse of Madness is a great movie that definitely enhances everything thus far in the Marvel Cinematic Universe since the Launch of Avengers Endgame.
The Movie by itself is a great watch and will leave you with laughs but also at the edge of your seat. The movie, of course, centers on Doctor Strange but also other Cast like Wong and Wanda as well as the new character America Chavez.
This Movie however does require background knowledge of Doctor Strange from 2016 and also some prior Marvel Knowledge to really grasp the Story to the fullest but isn't a big requirement as some of the characters are explained throughout the movie in summary by the main characters.
As for the overall Movie, I enjoyed this movie for the Story but I do have a couple of issues with the Film but also in general including the fact that most of the Plot Twists were spoiled by people online. For Avengers Endgame and No Way Home, not even those leaks or spoilers were as big or significant as those people were sharing like wildfire only a week after the film's release.
Listen, I know that Spoilers happen on the internet and that's why it's best to stay off the internet if you are looking to see a Marvel Film, however I thought that after No Way Home having almost no real game changing spoilers (that I saw) that people actually would respect leaving spoiling movies at a rest but NOPE. Just got to say, really would have loved to had the plot twists as suspenseful as they could have been but you know....guess people are just rude (in general terms).
In conclusion, while I did get rudely spoiled for a couple plot twists that were big, I definitely would recommend this movie to anyone with any doubts about this movie However maybe just go back and watch: Doctor Strange (2016), Avengers: Infinity War, Avengers: Endgame and Spider-Man: No Way Home before watching Doctor Strange 2. Maybe if you really need to understand who Wanda/Scarlet-Witch is then go and watch Avengers Age of Ultron and Cap. Civil War.
Overall I give it a 5/5 however with how much you really would need to know of Doctor Strange, Spiderman No Way Home among others, I give it a 4/5 for that reason.
Definitely would recommend watching some Marvel Films like and after Avengers Infinity War and the First Doctor Strange.
