Frequently amusing though it is, the you-go-girl comedy I Feel Pretty isn't great, but it does boast greatness in the fearless blond comedienne who makes the whole experience worthwhile. Hilarious and touching while refusing to deliver even one line in a predictable manner, this much-lauded performer, whenever she appears, turns what might've been a forgettable trifle into surprisingly resonant and satisfying entertainment. Her character also makes important points about self-image, biased expectations, and both blatant and hidden misogyny in offhanded and unexpected ways. I'm referring, of course, to Michelle Williams. But the movie's star isn't bad, either.
