It shows a lot of what her character and the movie is all about, but on a subtle way rather than actually telling it all. I wish it was longer though, not even 2 minutes... More of a "teaser trailer".
About her "bored" look, they already said sometimes her kree side is dominant and she isn't fully human. And on top of that she did get mindwiped to forget her entire human life apparently. So she probably starts the movie as a bit of a stoic soldier and as it goes on she becomes more and more human as her memories start coming back. Brie said on interviews that she was actually able to use her experience on dramas on this movie, because it has humor, but when it's serious, it's serious(what I REALLY appreciate becasue it's lacking on a couple of MCU movies).
I'm sure it was on purpose, like how it's released on Women's day. Marvel's pretty clever with those dates.
