I voted for The Wedding Banquet, which is delightful in so many ways. A film from the early '90's showing a normal, stable gay couple living an essentially married life. The cross-cultural parental pressures/conflicts which, while specific to the characters and their Chinese background, are still universal generation gap issues. It's light and fun, and in the films that follow show how Ang Lee is the master of showing characters who are repressing sides of their self due to society, family, and their own individual nature.
Eat Drink Man Woman is another delightful family comedy-drama, re-made as Tortilla Soup. I don't remember much of Sense & Sensibility (and may have it confused in my mind with Emma). Haven't seen Pushing Hands, Ride with the Devil or Hulk, and tried to watch The Ice Storm on TV recently but couldn't get through it. I really liked Crouching Tiger, Hidden Dragon, but would put it in the same category as Hero and House of Flying Daggers--and as such doesn't stand out as much for me.
