Sinister strange is supposed to be more powerful than it's shown in the movie.
As of storyline, it was good . Not so dark and horrifying as it has been told. Don't keep too much expectations comparing to the hype.
The best thing abt the movie is Wanda. Focus on Wanda is pretty good and the way it has been potraited is quite remarkable.
The story of this movie is going to be a stronghold for future mcu movies. And the concept of multiverse.
The bad things abt the movie is:
1. Sinister strange is not that noob. A variant who has all the powers of darkhold cannot be defeated so easily.
2. Captain Marvel cannot be defeated so easily . Yes, scarlett witch is more powerful but the fight should have been a bit longer.
