I really like the concept and plot of the movie. How someones life who strives for perfection and is living a particular lifestyle changes when a variable is introduced in it. How he deals with it is great to watch.
What I also liked about it is the kind of climax it has. Dont want to write a spoiler but in this movie, you might predict a few things but there will be other things that might surprise you, pleasantly.
I heard a lot of negative comment about Ben Affleck in general but he has played this role of Accountant very perfectly and is a real treat to watch.
There are a lot of things that can be taken away from this movie, and it is surely gonna occupy your mind for some time at least.
