This film sheds light on how people keep shuttling in and out of the same relationship because because they can't lose the 'habit' of loving and being loved by the same person, however incompatible and toxic they might have become for each other; because they think they are meant to be and they keep trying and trying to make it work till it drives them crazy. But just when this dysfunctional relationship has about tested your patience, the protagonists call it quits for once and all (or do they?!).
The movie shows that breaking up and moving on when you have been in a passionate relationship and you're both intense people sometimes, maybe very very difficult, but it is not impossible.
Do watch if you're struggling to let go of someone. I don't know why this movie is so underrated when it actually is a great attempt to capture the madness of a sinking relationship.
