Wildly imaginative, Eternal Sunshine practically bleeds creativity. God bless Charlie Kauffman for the things his mind dreams up. Gondry is the perfect companion for Kauffman's script, managing to let his sense of wonder (a trait that sometimes overpowers his films) flow perfectly with the tone and story.
Packed as it is with impressive performances from a cast of stars and character actors alike, one can't help but feel that there's something missing at the core of Anderson's nearly 3-hour thesis on human misfortune and experience. There's a powerful story here (several, actually), but Anderson gets lost among the multiple threads he's trying to pull together.
Of all the films in Wong Kar-Wai's impressive oeuvre, this is probably the most fun. The sweeping romance and lyrical melancholy are still there, yes, but there's an undercurrent of playful whimsy as well. This is especially true in the second section of the film in which Faye Wong brings her cheery spirit and pixie cut to WKW's color saturated universe.
Tony Leung delivers what I consider to be the best performance ever given by an actor. There is a scene near the end of the film when Kar-Wai allows us to see the character's tough exterior crumble that will stay with me always. Lyrical, quiet, and overwhelming.
Maybe one of the most devastating films ever made. Beautiful and heart breaking without becoming manipulative or oversentimentalized.
