The Iris Effect

My mother saw the movie before I did. And she told me to see it and try to solve some doubts she had about the movie. I saw it and really got confused during the movie, but I don't know if it's just me, but I'm really fond of this kind of movie that you get really confused , don't understand, but that in the end everything makes senses.....Plus it leaves in the air something with reincarnation, which in my opinion is a great topic.....moreover there's no exact end scene to the movie, there's no end at all.....it solely ends......just when you're trying to puzzle all the facts in your head. I don't know, this movie made me recall that one BIRTH in which the main actress is Nicole Kidman.... Despite in that one the love of her life was to had being born in the body of a boy. In this one there's also a boy but it's her son, and she's not aware of his death.
