The Matrix Reloaded: Neo vs. Agent Smith(s)
OK, so maybe the Wachowski siblings went completely off the rails with the second and third installments of this ill-advised trilogy, but the promise of the original chapter—those 360-degree fight scenes and slow-mo bullet shots that would be ripped off ad nauseum for a decade to come—was fulfilled with the Neo vs. 1,000 Agent Smiths fight in The Matrix Reloaded. Honorable mention here goes to the first Neo vs. Smith showdown from The Matrix that led to Neo's death and resurrection (spoiler alert from 13 years ago!).
