Can you imagine if right before that they have him say those things from Conrad Murray's recording:
Michael: "I’m taking that money, I’m building a children… children’s hospital. The biggest in the world. Michael Jackson’s Children Hospital. Gonna have a movie theatre, game room. Children are depressed. They’re in those hospitals, no game room, no movie theatre. They’re sick because they’re depressed. Their mind is depressing them. I want to give them that. I care about them, them angels. God wants me to do it. God wants me to do it. I’m gonna do it, Conrad."
Conrad Murray: "I know you would."
Michael: "All we have is this hope, no more hope. That’s the next generation that’s gonna save our planet. I’m starting with… We’ll talk about it. In the United States, Europe, Prague… My babies…. They walk around with no mother. They dropped them off, they leave – a psychological degradation of that. And they reach out to me – please take me with you. I want to do that for them. I’m gonna do that for them. That will be remembered more than my performances. My performances will be up there helping my children, it’ll always be my dream. I love them. I love them because I didn’t have a childhood. I had no childhood. I feel their pain. I feel their hurt. I can deal with it. Heal The World, We Are The World, Will You Be There, The Lost Children. These are the songs I’ve written because I hurt, you know, I hurt.
Conrad Murray: "You okay?"
Michael: "I am asleep."
And then the song starts playing as he "falls asleep"...
And remember what I told you ... And remember for all time... Please let me go... Please... Please... Please let me go...
Oh the heartache

I couldn't think of a more powerful message to end the movie with. A message that is not just about Michael, but also to remember all the children who suffer in the world.
