Singin' in the Rain (1952)

Director: Stanley Donan and Gene Kelly (I'll pass on examples since it was a joint effort)
Stars: Gene Kelly (An American in Paris, The Magic Lamp)
Debbie Reynolds (How the West was Won, too many to pick one)
YesNoSoso: 1

As stated on numerous occasions, I fucking hate musicals. If you like musicals, this movie would probably fall into an emphatic YesNoSoso 2, but you not me so shut up. There were impressive moments and was somewhat entertaining, but it was still roughly 2.5 hours of a dude singing and dancing.
