Ach, I just really like this film.
Its parts are greater than its full sum. This isn't so much a successful film, as it's at times a selection of fun pop-culture references.
Watching Spielberg do this is at times amusing, and enjoyable, but at others gives me similar feelings as new Simpson episodes. After watching a new one, I just really want to watch one of the old ones.
Ready Player One's appeal lies in how good the films are that it's referencing.
