Either make this a weird, unconventional friendship story or an all-out farce.

Would have been more interesting if just dealt with adult woman having a bit of a nervous breakdown who befriends a rebellious Teenage girl, who shows her their is more to live in life then men and partying. Just have both of them growing from each other's lessons. But instead they put in a stupid romance which came out of nowhere (love Sam Rockwell, but he deserved better) and it lost all what made it special for me. I disliked Knightly's character too.

I enjoyed the film with the romance - but yes, it might have been interesting if there was a meeting of minds, spikey friendship instead.
