A lot of hardcore fans of the superhero genre have criticised the newest addition to the Marvel Cinematic Universe (MCU) for bad CGI and questionable casting choices (mainly for Brie Larson as Captain Marvel) while comparing the movie to DC's Wonder Woman, which admittedly is way better than Captain Marvel.
Frankly, the movie was squeezed into the MCU timeline just to introduce one of the most powerful characters of the Marvel comics into the Cinematic Universe just ahead of the grand finale, 'Avengers: Endgame'. Even if some people decide to skip this one, there would be little to no information that would have been missed out on, maybe other than the mid-credit scene, which only looks like a scene from the movie.
However, if you did choose to become a part of Carol Danvers' journey to becoming the superhuman that she is now, you might have left the theatres with some new, unresolved questions in your head.
Why Did Fury Not Call Captain Marvel Before?
Let's start with the most obvious one. Danvers told Fury to only give her a shout for a real emergency. If you ask us, New York City flooded with an army of combat-ready aliens ready to invade the planet to subjugate its people does feel like a big emergency.
Why did he not, even once, mention anything about the strongest person/weapon he knew during the events of the first Avengers?
How Is Fury Aware Of The Acronym 'S.H.I.E.L.D.' Yet?
Throughout the movie, Fury calls his division - the Strategic Homeland Intervention Enforcement & Logistics Division - by its acronym, S.H.I.E.L.D.?
The events of the movie take place in 1995 when Agent Coulson was only a rookie. The idea of coming up with a shorter name for their organisation was clearly recommended by Pepper Potts during the first installment of 'Iron Man', which according to the MCU timeline takes place in 2008 and even then, Coulson said that they were “working on it”.
How Did Mar-Vell Get Hold Of The Tesseract?
At the end of 'Captain America: The First Avenger', we see that Howard Stark was able to salvage the Tesseract after Steve Rogers crashed the Hydra jet into the ocean. Also, Avengers (2012) shows us that the space stone was in possession of Fury.
Then how was it that Doctor Mar-vell was able to take away the Infinity Stone from the extremely secure hands of a top-secret organisation like S.H.I.E.L.D.? And if that was the case then why weren't Fury & Co. actively searching for it?
What Happened To 'Goose' The Cat/Flerken?
Late in the second half of the movie, Fury realises that the cat he got attached to so much so quickly was actually an alien of 'High Risk Level' who could swallow multiple full-sized humans consecutively. The Flerken also swallows the Tesseract and according to the post-credit scene, coughs it out onto Fury's desk.
But, what's next for Goose? Did Fury continue to keep him as a pet cat? Did he eat other people as well? Did he leave with Danvers on her expedition to free different worlds from evil? We need to know!
