It's been several hours since this was posted, so you may have well seen it by now. I'm thinking that's probably for the best anyway, since I would hate for what I might say about it add or detract from your experience.
I've watched every MCU movie at least once, and I feel like I need to see Captain Marvel again to give it a fair assessment. As of now, though, I would give it a seven.
WHY SEVEN?
I don't want to spoil this for anyone (including you) who hasn't seen it, but I would like to at least offer some reasons why I give it that score.
TRAILERS
I feel like most of the movie, and a lot of what was entertaining, action-packed, and important, with only a few exceptions, were in the trailers Marvel put out to promote the film. That's roughly three to four minutes. So, when I got to the movie, I felt like I'd already seen most of it.
STAKES
They weren't really that high. Since Captain Marvel is set in the past, we know nothing's going to happen to her (even if she wasn't being built up as the strongest MCU hero, meant to at least turn the tables on Thanos in Endgame if not do so singlehandedly).
But unfortunately, the movie doesn't really give us anyone else to care about enough, either. We know Fury's going to make it, along with some other beloved agents, and Carol Danvers' friend and daughter never really seem in peril, either.
MAIN PLOT
Carol Danvers/Captain Marvel can't remember who she is, and spends most of the movie with flashes of memory building up to a reveal and twist. However, it doesn't ever seem like that big of a deal. CM doesn't show much angst throughout, though she does get upset somewhat when she finds out what's going on. Otherwise, she's yucking it up with Fury and other folks, or at least trying to.
Then, when the twist happened, it didn't really work. Not for me, anyway. I can't say why or else I would spoil one of the few mild surprises there are.
JOKES FLAT
This may be because of the trailers, but things just didn't seem that funny. Or they came in odd situations. They seemed forced, and when that happens, it's worse than if there was no attempt at humor at all. In fact the biggest laughs weren't spoken, but visual. I won't say any more than that.
SKRULLS vs. KREE
This may be a personal issue, but the Skrulls and the Krees are mostly a distraction, especially when one Skrull speaks in an Australian accent and tries to be funny or sympathetic. I suppose there must be good Skrulls, just as there are certainly bad Kree, but it's just a little jarring how things are ultimately presented, and it's another thing that falls flat for me.
SUMMARY
After all that, you may be wondering why I even gave it a seven? That's because there are definitely some good moments, and in reality, Captain Marvel/Ms. Marvel/Carol Danvers is one of my favorite characters. I want to like the movie more than I did, but I don't think they did her enough justice.
If this movie had come out earlier, and not just weeks ahead of Endgame, maybe it wouldn't have felt so rushed together, or lacking in high stakes emotion. The one thing I can say did not detract from the movie was any showing of overt feminism that has been a big part of the build up to this movie. If there was a big feminist message in the movie, I missed it. I saw a superheroine who ultimately does what any male counterparts would have done—overcome her trials, kick backside and take names.
