From the movie Masterminds (2016)
In the beggining the main character is saying about the story of his life.
In 1997, I was a quiet middle-aged man knocking on 40. But then, then the wind blew in Miss Kelly Campbell.
Searching the Internet I learned that "look what the wind blew in" probably has the same meaning as "look what the cat dragged in" which a one says when someone that is disliked shows up. But in the movie the main character's saying the phrase about "the wind" blandly, like he actually was glad that Miss Kelly Campbell showed up in his life.
My question is - does the phtase mean only something or someone unpleasant or it has more neutral nature, like "But then she showed up"
