This one came out to be a bit different altogether, You couldn't just expect anything to happen as you had imagined, the next sequence of scenes was totally unpredictable and came with surprises at least if not with twists.
It was convincing enough that the whole film was based on sister sentiment but I think it crossed the line a bit with so much insistence on trying to register the same message multiple times across the film with some usual dialogues in certain places.
The message about friendship was registered so strongly which I think holds the movie together at least for me.
