Warning: SPOILERS for Captain Marvel.
Captain Marvel is a prequel to the other 20 films in the Marvel Cinematic Universe and it efficiently tells the origin of Carol Danvers without disrupting established canon, but the film still leaves behind a slew of unanswered questions.
Primarily set in 1995, Captain Marvel is about how US Air Force Captain Carol Danvers recovers her lost humanity after she gained superpowers and was kidnapped by the alien Kree. Under the command of the Kree Supreme Intelligence, Carol, who is an amnesiac, is renamed Vers and is made into a warrior in their elite Starforce, where she is supervised by Yon-Rogg. However, Vers is captured by Skrulls, who probe her hidden memories seeking the location of Mar-Vell's lab; Mar-Vell was a rogue Kree scientist posing as Carol's friend Dr. Wendy Lawson on Earth. She was using the Tesseract to develop a Lightspeed Engine to save the Skrull race from extermination by the Kree. With the help of Nick Fury, Agent of S.H.I.E.L.D., Carol eventually discovers who she really is and completes Mar-Vell's mission. After she gains control over her full abilities, she defeats Yon-Rogg and the Starforce, saves the Earth, and helps the Skrulls find a new world to call home.

Captain Marvel is a self-contained prequel that does drop a number of references and connections to the MCU and sets up how Carol eventually joins the fight against Thanos in Avengers: Endgame. While the film does an excellent job establishing who Carol Danvers is and why she wasn't around when the Avengers formed, Captain Marvel does raise a number of questions that the film left unclear or simply unanswered.

Why Didn't The Kree Experiment On Vers If They Wanted The Tesseract's Power?
When the truth about how Carol Danvers gained her powers was finally revealed, she used Mar-Vell's gun to blow up the crashed Asis' engine and the resulting explosion infused Carol with energy from the Tesseract. Prior to that, however, Yon-Rogg demanded the Asis' power source, which he believed was the Asis' engine itself. Presumably, the Kree also wanted the Lightspeed Engine technology Mar-Vell had invented and planned to give to the Skrulls.
But once the Kree kidnapped Carol, who had amnesia, and brought her to their homeworld Hala, why didn't they experiment on her to unlock the secrets of the Tesseract's power - since as far as they knew at that point, she was now the conduit of that energy? Instead, the Supreme Intelligence suppressed Carol's powers with an inhibitor chip and Yon-Rogg brought her into Starforce under the name Vers.
Why Did The Kree Want A Lightspeed Engine If They Already Had Interstellar Travel?
The true value of Mar-Vell's Lightspeed Engine needed a bit more clarification in the film. It was clear why the Skrulls wanted it; they were being exterminated by the Kree and needed faster-than-light travel so they could find a new planet as far away from the Kree as possible, and Mar-Vell, who believed it was an unjust war, was betraying her own people to help them. However, the Kree already had interstellar travel and an armada, so what was the value of the Lightspeed Engine to them?
This comes down to the somewhat ill-defined rules of space travel in the MCU. In Captain Marvel, and in the Guardians of the Galaxy films which are set decades later, interstellar travel happens by the use of Jump Points - the hexagon-shaped barriers in space ships fly through. They're essentially artificial wormholes, not unlike the wormholes that lead to and from Sakaar in Thor: Ragnarok. What Mar-Vell invented was the MCU equivalent of warp drive in Star Trek and jumping to hyperspace in Star Wars, which would allow ships to travel faster-than-light without the use of Jump Points, by harnessing the power of the Tesseract, which was really the Space Infinity Stone.
Why Didn't The Kree Want Vers To Use Her Full Powers?
Yon-Rogg kept Vers in line by repeatedly telling his protégé that he wanted her to be the "best version" of herself. This was meant to keep Vers from seeking out the answers to the questions continually plaguing her and maintain her Kree warrior persona. But since the Kree were using Yon-Rogg as a weapon anyway, why did they suppress her powers so she could only access a fraction of it? Vers could have been even more valuable to the Starforce and the Kree's war on the Skrulls if she could use her full abilities - they might not even need Ronan and the Accusers.
One answer is that the Supreme Intelligence feared that Vers would rebel if she could unlock her full potential - but why would Vers being able to use her full powers also return her memory? Are they tied together? Vers only found out who she was after she saw the redacted files about Carol Danvers at Project Pegasus. Perhaps the Kree feared that if Vers could do everything she was capable of, she would eventually just fly away from Hala under her own powers and seek answers. But even then, it seems the Supreme Intelligence cheated the Kree out of a great weapon by not utilizing Vers to her utmost when she was under their thrall. The Kree could have also developed weapons based on Vers' powers that they could use to stop her if she ever went rogue - which she did.
Did The Other Starforce Members Know About Vers Being Manipulated?
Vers was the star pupil of Yon-Rogg and she seemed to fit in with the rest of Starforce - although Minn-Erva admittedly never liked her. It's not clear if the rest of Starforce knew the extent of how Yon-Rogg and the Supreme Intelligence were manipulating and controlling Vers. Minn-Erva knew the truth since she was with Yon-Rogg on C-53 (a.k.a. Earth) six years prior; they attacked Mar-Vell's ship and Minn-Erva saw Carol exposed to the Tesseract's energy. But what did Korath, Bron-Char, and Att-Lass know about Vers and how much did they help maintain Yon-Rogg's deception?
