this be a very difficult movie and and it almost impossible to get a handle on what go on . at first it seem to be a rather pedestrian movie about a guy ( trelkovsky ) who need an apartment and rather crassly invite himself into one when the current tenant ( a woman ) commit suicide . then the twist and turn start . be the neighbor try to kill him . and why be the dead tenant clothes turn up in the apartment . one wonder and finally and if trelkovksy _is_ the prior tenant . spoiler spoiler spoiler spoiler spoiler spoiler one of the trick polanski pull on u be to lie to u . we assume when we see thing from the point of view of a character that we see thing a the character do and that there may be distortion of reality . we assume when the camera be show u thing from it omniscient point of view that we see actuality but polanski have the camera lie to u .
