Grease (1978)

Nearly all of this movie is pure delight. Fantastic musical numbers, likeable main characters... great stuff. And then it gets to the end and everything goes haywire. Sigh. (Spoilers ahead.) Sandy discovers that the only way to get her guy is to change everything about herself. That is NOT sweet or romantic. That's bleak and depressing. (Although possibly more justified if you consider that he was apparently about to become a jock for her - so at least they were going to mutually try to change for the other person.) Also, the lyrics for "You're the One That I Want" make zero sense in that context. "To my heart I must be true"? That's clearly not the case, since she's just changed everything about herself for a guy. Harumph. That lame ending lowered my rating half a star. However, I am going to salvage the movie from the mess it turned into, by pretending that post-movie they tell each other, "It's okay, you don't have to change, I really DO like who you are" and all is well. 3.5 stars.
