Keep in mind, that the Rotten Tomatoes Scores is simply a reflection of the % of critics who liked (or at least didn't hate enough to give a rotten tomato) a movie. It is NOT a letter grade. For example, a movie could get 100% on Rotten Tomatoes even if most of the critics only gave it a 6.5 or 7 out of 10.
If you look at the average rating, Jaws has a 9.2 out of 10 whereas Ms. Marvel has an 8.3 out of 10.
I still think that score is waaay to high for Ms. Marvel, but the vast majority of critics based their reviews on the first two episodes that were provided in advance. The show didn't really go off the rails until around episode 4.
