I confess. I like Musicals.
Everything about West Side Story is great.
The Hollywood Reporter said in its 1961 review:
West Side Story is a magnificent show, a milestone in movie musicals, a box-office smash. It is so good that superlatives are superfluous. Let it be noted that the film musical, the one dramatic form that is purely American and purely Hollywood, has never been done better.
Here is my favorite dance sequence from what I consider the most brilliant musical ever filmed.
