First half was bang it's feel like dhanush as king with crown in his head. But second half is as we know. Love between them is not evolved not hard hitting to audience when she betray the dhanush and the blast scene was poor cgi in london and mother emotion is more impactfull than the refugees emotion.The core is the refugee emotion and dhanush betrayal to sivadoss in that sivadoss emotion conveyed but refugee emotion is not upto the level. If I watched in theatres the first half bang will drive me upto the climax. I felt like sumarana screenplay for carring the emotions.
