This film is very difficult to follow and understand. Visually it is attractive, but its narrative line is deliberately twisted, baroque.
I like the sequences of the protagonist's suffering over the fatal step taken by his wife, a beautiful woman, and his innocent children.
A literal nightmare, and, like all nightmares, a recurring one.
The drama is also created by the soundtrack.
Dom Cobb (DiCaprio) is an expert in the art of stealing secrets from other people's subconscious while they sleep.
Cobb's uncanny ability made him highly respected in the world of espionage, but it also destined him to become a fugitive and thus abandon his regular life.
The only chance to change his life is to do the exact opposite of what he has been doing all along:
Inception, which is to implant an idea in your subconscious mind instead of subtracting it.
However, your plans are complicated by the intervention of someone who seems to be able to predict your every move, only Cobb can figure it out.
