@Runwildboys posted concerns about the future of the MCU. I re-read my comment after your reply. On second thought, I should have posted,
"The MCU, with Ms. Marvel, will survive and thrive despite any and all negative television reviews."
Disney has been proactive with announcing upcoming productions at comic-cons, investor meetings, etc., for over a decade. The company is a corporate marketing behemoth. They have overwhelmingly and repeatedly established their long-term strategic planning. Ms. Marvel is one particular character that is easily seen (in my opinion) having obtained a lengthy commitment from the studio.
One example of that commitment was the character's transition from page to screen. Ms. Marvel was not simply copied-and-pasted. There was serious decision-making in converting her Inhuman based stretching and morphing abilities, that were integral in making the character a highly popular one in the industry, to this other-dimensional based 'bangle' (side note: I think their inspiration still came from the original Captain Marvel's NegaBands concept, which would be a clever purposeful tie-in between old and new). It was a gamble with the character's core base but I think it has paid off handsomely. Just my opinion though.
The transition opens up many more
non-Jersey City/Earth based opportunities for her within the MCU. I think
The Marvels is just the tip of the iceberg in Feige & Company's future plans. So, early on, I believe it is highly probable the trio of Brie Larson, Teyonah Parris and Iman Vellani will duplicate or maybe even exceed Larson's initial worldwide success in her movie. And that 2019 movie flourished at the box office despite moderate reviews.
Rotten Tomatoes, Metacritic and
IMDB are my three go-tos for observing overall reviews. I have been closely evaluating the criticisms levied at the series. I have concluded overall negative audience sentiment will not have any tangible detrimental effect on the actress and the character's MCU future--and, by extension, the next MCU phases.
