Popular culture travels in waves. A decade or so ago, when every studio was trying to copy The Matrix and start their own action franchises dripping with self-serious stylization and slow-motion fights, I would’ve killed for a summer movie that took a grounded approach to heroes and villains. Now, after several years of Marvel movies and grimdark blockbusters, the pendulum has swung back the other way. It’s not that Guy Ritchie’s King Arthur: Legend of the Sword looks like a good movie, per se. It’s just that I’m in a place where I can really appreciate its goofiness.
