People hate on MI:II a lot but I think it's actually my favorite of the series purely based on the fact that it's the most different from the others and the action is much more stylized. Having studied Hong kong cinema and the films of John Woo, it's clear to see how Woo took his classic trademarks and meshed them with a big budget Hollywood blockbuster. Slow-motion, Ethan wielding double pistols, female-driven musical cues, white doves, and top notch fight choreography. That final fight on the beach is brutal and thanks to John Woo's mastery of fight cinematography, we can actually see everything that goes on.
Best moment of MI:II is when Ethan disguises the villain's right hand man with a mask of himself and the villain shoots him, thinking it's Ethan.
