I celebrate it. The best golden age MGM musical not actually made by MGM (but with Roger Edens, Gene Kelly, etc... working on it for 20th Century Fox).
The sublime production design, perhaps the best orchestrations on any musical film ever, Streisand's towering singing of "Before the Parade Passes By".... plus a "Best Picture" Oscar nominee at the time. And maybe more tellingly, a film that has not gone out of print since it was one of the first VHS videotapes issued at the dawn of the home video era (through dvd, blu-ray, and now streaming.). A film generously quoted in the beloved Disney/Pixar "Wall-E." As moderator Ryan Murphy told Barbra at their Paley Center evening recently, he celebrates Christmas every year with a screening of "Hello Dolly"! I celebrate it too!
