I just can't talk about this movie without going full spoilers. There's a lot to cover, so this will be on the longer side.
Depending on who you ask, Captain Marvel was either a perfectly fine movie, or the work of evil social justice warriors trying to ruin everything for real comic fans. This film, Captain America: The First Avenger, and Thor: The Dark World all have have a 6.9 rating on IMDB (at time of writing)(nice), but only one of these films has 6.2% of its ratings 1 out of 10. The other two have 1/10 ratings being 1.2% and 1.1%, respectively, for those keeping track at home. But what separates Captain Marvel from the other two? What about this titular character is different? Hm, I wonder, he says sarcastically.
Have you noticed that a good chunk of horror media uses easily recognizable creatures but avoids naming them as such? Like, those aren't zombies in The Walking Dead; they're "walkers" or "biters" or whatever. In 28 Days Later they're called "the infected." And in 2007's I Am Legend those aren't "vampires;" they're... actually I don't know what those creatures are supposed to be, but they're vampires in the source material. What I'm trying to say is I didn't hear the word "alien" in this movie until about an hour and 22 minutes in, despite just about everyone watching the movie realizing early on this is about aliens. The trailer's even less subtle!
