There is nothing quite like your first Wong Kar Wai experience, and Chungking Express was my first. Everything about it blows right through you and makes you feel things even before you're sure why you're feeling what you're feeling.
The styling is unbelievable. To me, this is as artistically amazing as Chinese films get. At every juncture he makes small but critical choices that transform the film into a really powerful experience. The stories themselves are relatively simple and straightforward, but they really build onto the style to make something utterly unforgettable.
You can't help but feel a little differently about what's possible in film after watching this.
