So, the main thing I took from this movie is after all that effort to stop him conquering Earth, when we actually see Loki get to be in charge of a planet, his main policies appear to be military non-interventionism and investment in the arts.
“Loki, I thought the world of you. I thought we were going to fight
side-by-side forever, but at the end of the day you’re you and I’m me
and… oh, maybe there’s still good in you but… let’s be honest, our
paths diverged a long time ago.”
