I hated them all
I couldn't stand any of these people. Ed Harris was a disgusting creep like Meryl Streep in Osage County...the annoying nurse who 'loved' him and knew more about the relationship w/ his son than the son did, and of course she just HAD to go on the road trip with them. Jason's weak character that easily bends to her even though he's made it clear he wants nothing to do with the ahole.
Horrible.
