Adam Goron’s review published on Letterboxd :
Singin' In The Rain is one of those movies that I never got around to seeing because I always sort of assumed that I knew what it was (Gene Kelly. Singing. Dancing. Puddles. Check.), and could therefore put it off. How wrong I was - sure, the film's a musical, but it was a great deal funnier than I thought it would be. There's some wonderful slapstick dance sequences, and a sly opening scene wherein Don Lockwood rehashes his life of "dignity" to his adoring fans - and we see through flashbacks that it was anything but.
I just recently watched The Artist, and that film culled several scenes from this one, but it was a joy to trace those elements back to their wellspring.
