As someone who writes narrative, I really liked the plot structure in this movie. I would only evolve Mara's internal conflict a little more, and I would give Gali a more closed ending after his realization.
But other than that, this movie was so worth watching. The acting was great and beautiful (my eyes were teary most of the time), the actors portrayed the characters' feelings so well. The special effects as in Gali's POV were so good. I think it is very important to be empathetic with the people around us, you won't ever understand their personal struggles, but you can choose to be a kind and understanding person to them (which is actually what we all should do), this movie also promotes that.
And, oh I desperately need to look for the movie's OST, it was just so perfect!
