Really good watch, would watch again, and can recommend.
I don't know if it's that Adam Sandler is playing a dying character, or that Seth Rogan is miserable, that the idea of being a professional comedian is especially appealing, or that they just did a fine job mixing a serious situation with a lot of comedy while mixing in some showcase of humanity, particularly human values.
There are a couple of really good "finding self" tropes in this. It's good to see "behind the curtain" of comedy. The cast is excellent, and not because he strayed from his typical Happy Madison group, but just... lees de rest.
