As a massive fan of the first film, I thought that this film was decent. Not amazingly memorable, but watchably passable . It had a strong start, and
Spoiler:
the introduction of the Illuminati (and thus the Fantastic 4 and X Men), the concept of dreams being multiversal gateways, the power/corruption of the Agents-Of-Shield-introduced Darkhold, and Scarlet Witch being the film's primary and seemingly unstoppable antagonist rather than Strange's sidekick
was highly intriguing. However the film seemed to fizzle out at the end, IMO because
Spoiler:
it pulls that lame TLOU2/"power of love" BS where the villain aka Wanda spends the entirety of the movie's runtime mercilessly slaughtering people, only to cop out at the last second and suddenly develop a conscience, thus rendering her relentless quest, and thus the entire film's plot, into an indecisive and meaningless waste of time in order to preserve the character's marketability. Also, IMO, Strange has weak characterization in this film compared to it's predecessor. In the first film, he underwent an amazing character arc going from selfish jerk willing to push around others to selfless hero willing to sacrifice himself, whereas here, his primary character conflict is the generic and boring "too busy being a hero to have a spouse" cliche. Also, Mordo seems to have conflict with Strange purely because the plot demands it, even when it doesn't benefit him or his superficially weak values in the slightest
While this was a fun movie in terms of spectacle and does have great fantasy concepts, it seems to be weighed down by its status as an MCU vehicle, which prevents it from becoming a fully developed standalone film. I'd give it a 7.5/10, as it was better than Iron Man 2 or Thor: The Dark World, but not as good as Guardians Of the Galaxy 2 or Captain America: The Winter Soldier.
