Okay, having arrived from my screening, I'll just lay out a few thoughts since I'm too tired to write a full review:
I found the movie pretty entertaining, but I don't think it reaches its full potential.
The non-linearity of the plot is a neat twist to escape the origin formula, but my problem is that they don't go up a notch in the action scenes. There are already very few of them, and when you think they'll pick up the steam, they're done. The final fight is the best one, and even then it feels too short.
I like the characters quite a lot, both Carol and the supporting cast. Brie does the most with the script she's given. You can tell she's still finding her footing in the beginning, but by the end of the movie she's more comfortable in the role. Her and Fury's partnership is the best relationship of the film.
Just wish her friendship with Maria Rambeau was more developed. Talos was suprisingly charming, I liked him a lot.
Yon-Rogg was meh, competent and that's it. But I LOVED Anette Bening as the Supreme Intelligence. Think she would've made a better main villain for the movie.
About the big twists: One was kinda predictable, but the other was quite a surprise for someone like me who has just a basic knowledge of the comics.
Also, the exploring of her past is way too rushed. You get glimpses on the flashbacks, but IMO not enough to create the necessary sympathy for the character. You can tell they didn't want to double down in her past with fear of forcing the more feminist themes.
People argue the first act is slow, but I'd argue the second act is the slowest of the movie, do to the things I said about not developing her past in its entirety and her relationship with Maria.
Overall, it is a fine movie. Even with the unique elements, its still an origin story that is stuck in the boundaries of the larger MCU. Its clearly just making way for her in Endgame and the future of the francshise.
But even so, I think its one of the better origin stories in the MCU. If I were to rank them (just the origin movies) would be:
1. Guardians of the Galaxy
2. Captain Marvel/Doctor Strange
3. The rest
I'll agree with something I read in some reviews: Brie will probably grow with the role and turn it her own, much like Chris Evans/Hemsworth with their characters. And she'll also probably go through the same as Doctor Strange: be more liked in the team-up than in this movie.
One of the bigger entertainment sites here in Brazil went to visit the set and the reporter told us she could see Brie Larson looked like she still hadn't grasped the escale of the role and being part of a franchise this big, and as herself admitted, she is an introvert and deals with anxiety, same as Chris Evans, so I'm sure she'll get better with time and people will warm up more to her.
People clapped at the end of my screnning. I really can't wait to see her in a group and how the Russos utilize her.
About the post-credit scene: First one everybody went wild. Second one, laughs. Nothing unusual.
