You knew whether or not you'd watch this movie tean years ago.

Rating: 5/10 (10 March 2019)

While this was an ordinary action movie, it is (I think) the 21st outing for the MCU. If you like the MCU, you'll watch it. If you don't, you won't. But if you're on the fence, this probably won't encourage you toward the series.
Brie Larson was fine; maybe a touch wooden, but she was a military type, so that could have been stoicism (whatever you feelings on stupid statements she has made, she didn't bring the movie down.)
Sam Jackson was Sam Jackson - coolest BAMF in Hollywood. Being that the movie was set in the past, the visual effects of de-aging him were amazing. His plot twist that you've probably already heard about is probably the biggest disappointment of the movie. This is not a reflection on Sam, but lazy, inept writing. Don't get me wrong, by Hollywood standards the script was about average. But the character deserved better.
The backstory was a lot like Green Lantern, only it made less sense. For what it's worth, it's fairly true to the comic, but even for Marvel Comics, Captain Marvel has a weak story.
The villain/s? Garbage. I'd say what I really think, but I don't think that kind of language is allowed on IMDb. Without spoilers, I will say this - you will hate the villain. I know you are supposed to hate the villain, but you will have an extra reason to hate this one - this one make the movie less fun to watch.
We've been hearing about how feminist this movie is. I don't recall much issue being made of gender. I most definitely AM anti-feminist, I am an egalitarian. Ant this movie wasn't particularly feminist.
So in short: Weak lead character, weak script, weak plot, and a villain that brings the movie down. Average action sequences, some laughs. Amazing supporting character, fantastic special effects. A solidly ordinary movie.
