I love a movie with a dance sequence, particularly one of those impromptu dance sequences where a large group of people who are just sitting around suddenly get up and bust into a choreographed dance. Think of such great movies as Grease and Dirty Dancing and 13 Going on 30.
My dream is to be in a dance scene like that, in real life, even though I have no dance moves to speak of (other than the shopping cart and the sprinkler, of course) and things like that never happen in real life, unless you are talking about a line dance at a country bar, which obviously I am not.
In any event, (500) Days of Summer was a wonderfully delightful film with the added bonus of a dance sequence.
We need more dance sequences in our lives, I think. Especially ones with the so adorable Joseph Gordon-Levitt.
