The Fall is a film that complements itself, and does it very well.
You could perfectly identify how the first half of the movie is very different from the second half. At first you may get the feeling that the best part of the film is around the end but the truth is that the film gives you scenes that have their importance and although at first they may not seem to have a relationship or logic, the truth is that the dramatic weight that would come later would feel a little empty.
This distinction between one half and the other goes beyond the scenes, as I said it is also noticeable in the dramatic tone, it is noticeable in the performances and how these cause the characters to seem very very different from what is first presented to you.
The film puts you in a comfortable situation and makes you feel arrogant thinking that what you see is poorly done or incoherent. For the most attentive, perhaps what happens after the halfway point is predictable because the film does not hide it or conceal it in any way. Excellent way but even if you know where the film is going you may not be really prepared since the scenes that show those predictable and successful conceptions will leave you perplexed.
The Fall is one of the examples of how to build three-dimensional characters, how to show trauma or depravity in plain sight and you not realize it and even if you do, its quality is notable and outstanding.
