There are a lot of people who feel that Captain Marvel is not supposed to be stronger than the other characters in the MCU because of different reasons. There are some who say that this is not possible because she is a girl which is a very feminist remark. There are some who say that she might be too strong and she might overpower everyone that she will encounter.
There is also a possibility that she will overpower not only her opponents but also the people that she is supposedly helping. He strength may be a good thing but how useful is this going to be in the long run?
