That list is obviously coming from a writer or group of writers with no real background in the history of the movie musical.
Off the top of my head, missing from that list: Sweet Charity, All That Jazz, My Fair Lady, Whit Christmas, and Hedwig.
Hell, I'd even put Hair, Pajama Game, Lil' Abner, Dancer in the Dark, 8 Women, Bells are Ringing, There's No Business Like Show Business, and several others over some of those titles. Hairspray wouldn't even be on my top 50. And I liked the film.
If any single musical film from the last 5 years deserves a place on that list it's Sweeney Todd.
