Whats wrong with me

It seems that a lot of people like that lady Emily Blunt, to be honest I have no idea what is so great about her. I have seen her in Dan in Real Life, The Great Buck Howard and The Wolfman and theres absolutley nothing special about her in those movies. I am interested in seeing her new movie with Matt Damon, only because its Matt Damon and it looks pretty cool. But Im asking the people out there in Listal world is there a movie that can change my thinking of her, I would like to know what that is.
