Sure - it would be impossible not to love a film whose actors include Harvey Keitel, William Hurt, Forest Whitaker and Stockard Channing. But it's the writing, too. The characters push against their stereotypes, and are good - they are - and the movie's about that. How to be generous and good within life's weirdness. The storyline is compelling and unpredictable.
The advertisement makes it look like a screwball comedy. There are some light moments, but they have a real humanity, and the dark moments do too.
I'm late to the party on this one, but I bet it's a film that reveals something on each viewing. I'm putting it on my watch-in-a-decade list.
