I absolutely loved this.
I have tried going into more films with less pre-concieved notions about what to expect and hadn't heard much about this before actually sitting down to watch it. Lively was dripping with swagger every scene, Kendrick continues to knock it out of the park, and the story bounces you along after the first 30 minutes sets the scene. Once the ride gets going it has very little time to stop 'to smell the flowers' as you trundle towards the ending.
Some of the story beats are predictable, others are less so, and to an extent once you get to the close of the film you can start to see what is happening before it does. But that is not the sign of a bad film, as it leaves many clues ahead for you and is fundamentally a Hollywood picture.
I had an absolute blast watching this.
