Simply put, it is the most beautiful movie I have seen in a long time. It tells a beautiful story. But actually rather than one story, it gives you a lot of lessons. Understanding life's simple joy, love, ego, forgiving others and yourself, and unity, while telling the bigger story of Klaus. It doesn't drag you by making the movie over dramatic. Even though we know what the end is going to be like, it was different. It was a happy ending, with bit of sadness and hope. And what can you learn from this? "A simple act of kindness always sparks another". With that message, the movie, in my mind was perfect.
I would like to talk about the animation and everything else, but it's just perfect and I am not a professional to talk about movie errors, and I rarely feel satisfied after watching a movie.
Just love it.
