The interplay between the 3 really seems like the selling point.
That was my takeaway as well from watching the trailer.
The plot looks like another cookie-cutter episodic entry. Them switching places each time they use their powers feels more gimmicky than compelling.
But Ms Marvel is adorable and so I think any positive word of mouth will come down to how wholesome the interaction is between the 3 women.
At minimum it has to be a smart & charming chick flick that you’d want to take your daughter to.
