My problem with Captain Marvel was the writing and direction of the character. We're often told about things in the world but not shown them, her character arc was flimsy and not put together very well, and unfortunately (imo) she's just not particularly likeable. The movie presents her as having somewhat of a chip on her shoulder, which is fine, but then it doesn't really do much to address it. Her character "flaws" aren't a detriment to her goals (Whatever those were) and as a result, there's no internal conflict. She doesn't have to grow past her flaws to reach those goals, so I had a difficult time relating to her character.
