Ready Player One is stock full of references to popular culture and involves an interesting easter-egg hunt in a world so crapsack that almost everyone has resigned to virtual escapism, even while they are forced to stack dilapidated (formerly) mobile trailers on top of each other...
What is confusing however is the odd absence of any government, despite the society being portrayed as somewhat orderly-with obvious exceptions related to the plot. This government then shows up just in the nick of time... Like some kind of prescient script armour for the protagonist.
The set design and worldbuilding is wonderful however, and the fast-paced animation is certainly a treat for the eyes. And for a movie about teenagers, the acting is also impactful and genuine... Maybe not best utilized by some silly plot moments.
