This movie rubbed me the wrong way; even the usually pleasing sight of Jennifer Aniston couldn't save it. Review-type spoiler: the fictional characters in this movie think fictional characters in another movie—specifically, The Graduate—are based on them. Even more specifically, Shirley McLaine thinks she's Ann Bancroft, Kevin Costner thinks he's Dustin Hoffman, and nobody thinks she's Katherine Ross, because (it turns out) she died. Ms. Aniston plays her confused daughter who's trying to resolve a personal crisis by straightening out her family history.
There's a lot of dialog that thinks it's funnier than it is. Performances are pretty flat, except for Richard Jenkins, playing Jennifer's dad; he actually seems to care about giving a nuanced three-dimensional performance.
And Kevin Costner's character gave a speech that referred fawningly to Che Guevara. This knocks the asshat score up quite a bit.
Otherwise, the word that kept going through my mind while watching this was: plastic. Ironic!
