I love Stardust Memories and who Woody Allen seems to have been at that specific moment in time.
Woody, the half-man/half-child genius in his number 24 t-shirt and glasses. The minimalist stark white apartment (with the giant Eddie Adams photo "General Nguyen Ngoc Loan executing a Viet Cong prisoner in Saigon" on the wall), the Fellini 8 1/2 homage, Gordon Willis' lush, black and white cinematography, The twilight scene at the end with the circus performers. The Django Rheinhardt music.
The elements are all there, and even if it's not a perfect movie - it captures something - some essence of his (and life's) creativity, humor and sadness -that I'll always find magical.
