Agreed and the same thing can be said of Fred Astaire movies with the formula being:^^
Gene Kelly...An American In Paris...I'd like to say it was one of his best, but on closer examination Gene Kellys scripts all seemed to follow an incrementally more familiar plot line, each set in a different location. However, as an actor, Kelly did give the viewer a lot of bang for his/her movie buck(s)!
Astaire + pretty female dance partner + exotic locale or upper-class society setting + minor issue(s) thwarting his efforts to attract pretty dance partner + some other plot nonsense + a bunch of song and dance numbers (the whole reason for the movie) = successful movie that makes plenty of money
Laugh (as I do sometimes, while still enjoying the movie), but it worked for three decades for Astaire.
