This movie is much more than a conventional romance, with the typical meet-cute sequence and plot-convenient obstacles that get neatly resolved. I'm thinking of the typical American Meg-Ryan-Julia-Roberts movie, where everyone is inexplicably wealthy, no one has any real problems, and all the "wrong" boy/girl-friends are shrews or dorks ... so the audience has nothing to do but wait for the inevitable and unrealistic end.
This movie represents some other real-life complications, such as coping without a lot of money, and shows the characters struggling with, and taking responsibilities for, their relationships and commitments.
The two leads, Maggie Cheung & Leon Lai, are terrific. Also wonderful is the supporting performance by Eric Tsang as Pao Au-Yeung. This is a thoughtful and beautiful movie about real people and real love.
