Beautiful Boy
it must've been hard for a parent to watch their child suffer --- especially with Steve Carell's role, who watched Nic grow up to eventually witnessed his son's pain. And when he sang Beautiful boy hit me really hard.
I love the fact that Nic's parents didn't abandon him but chose to help him instead. He may have gone back to his addiction multiple times, but his dad really did his best to help him. Even though when he thought of letting Nic on his own, he still went to him in the end.
