The relationship is so unresolved that it isn’t even incestuous.
This is an excerpt from the film review (Mother: Joon-ho Bong). Because I know the movie whose plot is based on the strong relationship between the mother and the son I have tendency to understand the above sentence in this way: The relationship is so strong that can indictae incest. But the word-for-word translation says the oposite which does not make me sense. Can you please tell me the precise meaning of the above sentence?
Here is a longer excerpt from the film review:
Won barges through the film, conveying the confusion of a stunted child desperate to break free, only not before dinnertime. In several overhead shots, Bong shows the pair in bed together, Do-joon’s hand clamped around his mother’s breast as if he’s a nursing baby, their raft-like mattress a sanctuary. The relationship is so unresolved that it isn’t even incestuous. Rather, it’s a murky fusion of parent and peer reminiscent of Roy and Lilly Dillon in The Grifters.
