Captain Marvel tells the story of Carol Danvers, an intergalactic warrior caught between space and time, learning how to make sense of her powers while trying to remember who she is. Marvel, played by Brie Larson, joins a young Nick Fury (Samuel L. Jackson) as they uncover a secret alien invasion by a race named the Skrulls. Fury learns that Carol is also part of an alien race called the Kree, who have been in battle with the Skrulls for centuries. The film goes on to reveal a deeper plot, all chronicling the origin of Captain Marvel and how she fits into the grand Marvel Cinematic Universe (MCU).
Captain Marvel serves the purpose of introducing watchers to the she-ro and providing her back story. Being that she pays such a large part in Avengers: End Game, her solo film is essential going into the final showdown with Thanos (albeit a little late to the party, IMO). Cpt. Marvel stays true to the spirit of the MCU, full of action and one-liners. But where it really shines is in its display of Marvel's powers. Being that she's a cosmic being with cosmic powers (not easy to pin them down),you'll see Carol flying and blasting around, with energy bursts behind and in front of her, energy everywhere. And Sam Jackson as a young(er) Nick Fury is a comedic delight. It can be said that the movie serves a greater purposes in showing young girls a strong female in Captain Marvel, and how she overcomes various opposition and obstacles throughout her life. Believe it or not, this is Marvel's first film staring a female role.
If you've been watching the MCU films then I KNOW you're ready for Avengers: End Game. Captain Marvel is a good entry in the Marvel train, whether you catch it at the movies or at home when it's released. Either way, we're definitely going to be seeing more of "Ms. Marvel" (more on that later).
