I hated this movie so much, I actually turned it off. So I honestly don't know where it ended up but I can guess because it seemed pretty basic.
It was just complete nonsense. None of the dialogue or actions made sense. Losing a parent is hard even if you have a strained relationship with them but these characters didn't act like actually people. They just did "funny" stuff. Nothing seemed to follow on with the characters they created. The brother is a republican yet cares about climate change? I know I'm generalising but most republicans either don't believe it or ignore it. Things like this drove me insane. Then the sister says "let's sleep in the van" while in the van and the brother had to point out "oh well we can't because of all them boxes in the back of the van". Like why!!! She can see the boxes, she has been driving in the van right next to them!!! And why not take them out before you set off!
It drove me insane but Aunt and Uncle Caricature really took the cake for me, that's when I had to tap out.
