The film is entertaining, of course, but in my opinion, Nolan has lost his way. The story wants to go further than it can in itself.

First, the principle of operation of the Tesla coil is that it ionizes the air and allows wireless transmission of electricity. And yes, I criticize it because in the same movie they talk about selling a magic trick and at the same time they put this _Deus ex machina_ with shoehorn: the machine's ability to magically clone (never better). At the end of the film you see that the machine has an emitter and a receiver. However, with cats and hats it is not like that, they just appear out of nowhere in the garden. It is annoying that the film justifies itself simply by saying "it is science". Jules Verne in almost all his works or Mary Shelley with _Frankenstein_ tried to conceal science fiction, or at least make it credible, with words and not lightning and sounds. The main problem of this type of events is that, when the lack of internal coherence is perceived, it produces discomfort. On the one hand, it is an easy method to obtain the desired plot, but it has also made the whole thing not credible or even bordering on the absurd.

On the other hand, in my opinion, the dialogues are a bit lazy. It's impossible to believe that the characters in the story said all that nonsense with conviction. I refuse to believe it. Likewise, the existence of the twin brother is not credible, let alone that he cut off both fingers on purpose by magic. In other words, according to the film, the brothers have decided to live by swapping roles with fake glasses, a wig and a moustache and mute for the rest of their lives and sharing scars with each other. Ah! and the worst thing is that the death of one of them has not affected the other brother at all, instead he has gone to his former best friend to shoot him and tell him the story of his trick.

In short, entertaining to watch on TV on a boring day, but not to watch again.
