So I'm watching Captain Marvel on blu-ray, and it strikes me that Brie Larson is nowhere near as flat as people were complaining. Even when shes's the brainwashed Vers, she's got a wry sense of humour, but it's just very restrained. She cracks little jokes throughout the movie, and you can see her opening up and getting looser, the longer she's on Earth and around humans. But she never quite reverts to the carefree woman we saw in the flashbacks.
It's actually quite a subtle performance, but I guess a lot of people were too upset she didn't smile enough to see it.
Also, Talos being challenged to turn into a filing cabinet, a cat ("what's a cat?") and a Venus Flytrap is such a fun little scene. He has this long-suffering, weary air about him, as though he's thinking, 'this always happens when we spend time around other races.'
