Frustating and boring

Rating: 4/10 (8 March 2019)

English is not my native language, so I apologize for spelling mistakes, I spent 10 years watching MCU and 20 years reading comics, I liked most movies, but marvel disappointed me before with IM2, IM3 and Thor 2, but these movies (IMO) were not as tedious as CM.
Leaving politics aside, what i like
Samuel L. Jackson, Stan Lee's tribute, Ben Mendelsohn, CG and The Cat.
What i dislike
Brie Larson's performance (not all, but most, she seemed bored for most of the movie), 99% of the jokes, the sex-change of an iconic character (Mar-Vel), the predictable twist, OP, the origin of the avengers (completely ridiculous).
and about the politics of the film: yes, they have a feminist / man (white) hate moments, it's not the same level as ghostbusters but is not that subtle, especially the flash backs, all white man telling her she is not good enough and she should quit and the biker scene.
Now I'm worried about Avengers: End Game, if the CM defeats thanos or have more screen time than the original cast, I'll never spend money again to see another marvel movie.
