There are hundreds of reviews floating round the internetsphere so I won't take up your time with mine, instead I'll share a few thoughts and then dive into, why the media circus?
SPOILERS AHEAD
I haven't read the comics. I should start that for every Marvel film I write about, although I used to read a bit of Xmen. Back to Capatin Marvel. Serving as an origin story for Captain Marvel aka Carol Danvers as well as side flashback to when Fury wasn't the head of S.H.I.E.L.D and was inpired by his encounter with Danvers and the all the other, aliens, to start his avengers inititive. This really makes Danvers the centre of of the whole universe so its only appropriate that shes there in Endgame to save it.
Starting with her day to day solidering with the Kree where they make sure she keeps her powers in check, answers to her superiors and encourage her to ignore her memory flashbacks, she is in deep with this life. Although their enemy are the shape shifting Skrulls, the Kree have never been the 'good guys' so it's not so difficult to see what comes later, despite the opening group banter, which was funny. Danvers or 'Vers' as she is affectionately known as literally crash land back home after escaping the sinister Skrulls ships and memory contraption. This is a homecoming that sets the whole 'but who am I' journey in motion, while at the same time uncovering the true deception of the Kree and switching the Skrulls to the innocent party.
Captain Marvel is a superhero film so it will hit the same beats as the films before it, but it also goes against the grain. She is superpowered thanks to an accident or rather act of bravery; trying to destroy technology that is literally from another planet and honour her mentor. The origin stories of Danvers have apparently been different and usually involving a man, soilder giving him her powers, BUT in this story, her mentor is Mar-Vell, a Kree scientist trying to stop war and its Annette Benning. Fantastic cast choice, in fact the Captain is surrounded by great characters/cast, which can make or break a film.
There were several times where I rolled my eyes but with homages to previous superhero films and even an Indiana Jones moment, the film was what I hoped to see. A fun, comic book film with an amazing and on point 90s soundtrack, featuring a fair amount of female artists and unexpected surprise in the form of a cat that provided comedic bits galore, I was entertained. It didn't excede my expectations but I enjoyed the outcome.
------------------------
There have been a great show of support between female film critics, sharing each others reviews on Twitter. I didn't read them all but the ones I did show a variety of reactions to the film. Some loved it, others didn't, some had strong feelings about different aspects surrounding the film, others championed it, and some, well, really hated it. Even amongst the positive praise and justified critiques, I was disappointed by the circus of attention that wasn't about the character and story.
The bigger picture is that, yes, there was quite a bit of the Marvel franchise riding on whether this film would be successful or not. But looking back at the previous films, there hasn't be a film thats been attacked (both positively and negatively) in this way before. I suppose there was a fair amount of speculation around the first Guardians of the Galaxy as it was purely space set and had three main characters that were CGI but that was because there hadn't be such a heavily sci-fi Marvel film, when really, if you strip it down, its a science fiction film with a great group of characters that just so happens to be within the Marvel universe. Also, its my favourite Marvel film. But apart from GOTG, the hype has been normal. I can't be the only person to have said this, but all this fuss is just because the main character, main superhero is female and to be honest, there shouldnt be this sort of hype just because of that fact. Extra pressure is mounted on this fact alone as to whether its good or not and if it isn't its because its a women front and centre and if its good, its only because theres finally a female superhero as the main character.
This is the death that practically killed Ghostbusters back in 2016. This is the death that buried Oceans 8, although granted the hype was not big for this film, which I don't understand, that film is amazing and I'm just saying that because I watched it 5 times in a row (no joke). This the possible death that Wonder Woman defeated, but because the rest of the DC films sunk (apart from Aquaman I hear) after the sequel, who knows what will happen to her. All these film were built up with everyone half hoping they'll fail. The malicious half anyway.
There has also been a cloud of disgust surrounding critics. A barrage of outraged critics who believe what they have to say is more important. Then the backlash that women only like the film because there's a woman in it! Its reached ridiculous heights. But, again, seeing the threads of female critics sharing each others work, no judgement, no arguments, just sharing and championing each other, gives me hope that we can do this for any film and not just when there a female superheo on the poster, alone.
