How to Be Single (2016, on Netflix) - a by the numbers, big-cast romcom that is above average. A strong cast (Leslie Mann, Jake Lacy, Rebel Wilson, Allison Brie, Nicholas Braun) help the movie along quite a bit, although I am amazed that this movie grossed over $100 million.
Dakota Johnson is gorgeous, but has no charisma at all, so it is strange that she is an A list star. Unless the camera is right on her, you end up looking everywhere else but at her.
The movie is based on a book by Liz Tuccillo, who also wrote He's Just Not that Into You, which was also turned into a movie. Those are her only two books, and both were turned into hit movies. I wouldn't say either are that good, but she clearly hits a chord, and I am surprised she has not done anything else.
