Aye it does a bit. A lot of philosophical monologues.
Excellent portrayal of near future space technology.
It brought up a lot of potential issues around country's implementing a kind of cold war on the moon over resources then it just ignores all the themes and questions it raises because in one of Brad Pitt's character's psyche evaluations he mentions that he ignores everything that is not essential and so all those things are irrelevant to him.
In the end it just boils down to him and his abandonment issues while he calmly goes about completing his mission.
There's some weird space monkey stuff too. Literal killer monkeys in space eating dude's faces off.
