Vincent Canby wrote in the New York Times: “Trelkovsky exists. He lives in his own body, but it`s as if he didn`t have a lease, as if he could be expropriated at any time for listening to the radio in his head after 10 P.M. People always knock on its walls.  When Trelkovsky occupied the apartment, he was repeatedly chastised by his neighbors and owners Mr. Zy (Melvyn Douglas) for having organized a party with his friends, apparently left a woman, made too much noise and did not participate in a petition against another neighbour. Trelkovsky tries to adapt to his situation, but is increasingly disturbed by the apartment and other tenants. He often sees his neighbors standing still in the bathroom (which he can see from his own window) and discovers a hole in the wall with a human tooth stored there. He discusses it with his friends, who do not find things strange and insult him not to oppose his neighbors. He goes to the apartment of one of his work friends, who plays a walking band with a noisy volume. A neighbour politely asks him to turn off the music, because his wife is sick and tries to sleep. Trelkovsky turns the record, but his friend tells the neighbor that he will play his music as he pleases and that he does not take care of his sick wife. A tenancy agreement is a legally binding contract between the landlord and the tenant.
So if you sign a lease in a new apartment, read everything carefully and make sure you understand what you are doing and agree not to. If you break one of your lease conditions, your landlord can sue you or charge you penalties for breaking the lease. You can sue your landlord or withhold your rent if he does not meet the obligations outlined in the tenancy agreement. “A lot of effects stem from the absurdity of the scenario where Trelkovsky only bothers someone, but everything Trelkovsky does is considered a constraint.”  Unlike the works of Franz Kafka (see below), the film is even more mysterious, whether it is part of the genre of horror or psychothriller, it has critically compared the two contemporaries Don`t Look Now (1973) by Nicolas Roeg and Stanley Kubricks The Shining (1980) even more than the two previous articles on Polanski`s apartment trilogy.
