I liked it. I like the idea of the story that invisible things become visible such love, time and death. Also I like that three of all connected to three of them who were trying to help Howard from being in deep grief over the loss of his daughter. All actors are pretty fitting in their roles.
What made me impressed and admire this is the the script of the movie. I really liked it.
This can be better and go deeper if it has more time.
