Ugh, the daughter-in-law
First of all, I just want to say that I really enjoyed the movie... it doesn't pretend to be more than it is, even with Meryl starring.
Anyway, the only problem I had was the daughter-in-law, Emily, I mean, talk about snob. To me, she came across very unpolite and rude from the moment she met Ricki. I know she's the fiancée, but to me she's trying to butt in a family problem that doesn't concern her... how tacky to try to justify not telling her about the engagement and not inviting her to the wedding with moronical excuses. Son and mother have a problem, let's keep it that way. And jeez those snooty wedding guests, looking her up and down. And I understand the daughter-in-law was embarrassed during Ricki's speech - she couldn't know where it was going -, but again with the attitude? I could almost see her eyes rolling to the back of her head. In the end she relented, and so did everybody else, because the mother of the groom actually knows how to rock, but I wanted do slap some sense into Emily.
I know some people feel entitled and what-not, but truly educated people never act that way, even if your significant other has a problem with said parent... You can obviously take that "You have a problem with him/her, I'll have one too" stance, but unless that person actually does something that warrants your bad side, it's so disrespectful to act as if you have a chip on your shoulder.
