So Chow and So are both intertwined between reenacting and love, but even though this love happens, neither act on it intimately in any way?
Why wouldn’t they have acted upon it if they truly wanted to?
Who is the father of So’s son?
In 2046 (the film) Chow is attempting to rekindle his only true love that he never acted on?
I think the film is rather straightforward. For social and ‘moral’ reasons, the two never do anything more. The father of the son may have been left ambiguous on purpose.
What comes down in ITMFL is social dilemmas & thinking of what is morally right or wrong. The couple try to place the pieces of their lives after both of them suffer a crisis. Neither know whether it’s right to sustain a relationship that goes against traditions. Neither know how to express their feelings & whatever they do is in self-doubt because they are concerned over social expectations and the reactions of their neighbours & well as their spouses.
What it comes down to is (as Roger Ebert said), “They are in the mood for love, but not in the time and place for it.”
