I went into Captain Marvel as blind as I could. I never watched the trailers, and had only seen a couple screenshots or gifs, and a poster. I had heard of people absolutely loving it, some thought it was mediocre, and others hated it, so I was open to just about anything. What I watched is by far the worst of the MCU movies. The movie fails at its core, centered around a character that is confusing, unlikable, and what I can only describe as bipolar. But I'm getting ahead of myself. Here is a spoiler review of Captain Marvel. (The only thing you need to know from this movie before Endgame is she gets her powers from the Teseract, and she shows up on Earth)
