I Haven't seen Captain Marvel yet and the crazy thing is I'm hearing mixed reviews. Some people are raving about it. Others think it was a terrible production. Either way, you HAVE to watch it AND the ending credit scene to understand what's about to happen.
Captain Marvel was the final piece to the puzzle in this Marvel Cinematic Universe. After her it's END GAME.. All characters form together to try and defeat the evil Thanos. Now whether they do it or not, IDK.. But watch the trailer they dropped to get you hyped. It's the beginning of the end.!
