Beautiful Boy
This movie was heart wrenching. When David realized that he couldn't help his son, it was so sad. Nic kind of reminds me of Jesse Pinkman. He seems like such a tortured character and you can tell that he knows he needs to change, he just can't, that is the saddest part of the whole thing. David loves Nic and he wants to help, but he sadly realizes I feel that sometimes you just can't help and that can be the worst feeling to have, because it is true.
I also think that whenever you have a comedy actor in a dramatic role, the movie is going to be amazing.
