The protagonist of Je T'Aime, Je T'Aime, Claude Ridder, spends the majority of the film adrift in time, randomly surfacing at various moments from a tragic love relationship. The viewer enjoys being flung forwards and backwards in time, to piece together the story...or, not.
The plot owes a huge debt to Chris Marker's far superior La Jetee, in which time-travel, love, and self-knowledge form a closed loop. Je T'Aime, despite its fractured chronology, is in fact more akin to a conventional tragic love story.
Director Renais was born in 1922, making him 46 in 1968 at the time this film was made. I think this is visible: Renais was perhaps too old to really feel and understand the 60s and its anarchic energy. While the film's time machine looks borrowed from "Barbarella", and the time-fracturing sometimes has a psychedelic quality, Renais' world-view is that of a man of the 1950s. (The hero is a WW2 veteran, firmly locating him in an earlier era.) The film is about existential dread, the weight of history, damaged and intractable male subjectivity. Meanwhile in Paris, in May '68, young people were rising up and discovering new forms of life.
The major flaws of the film are Claude Rich's unsympathetic performance as the protagonist, and a script that somehow leaves the love relationship feeling flat.
An interesting thought experiment: if the lead actor had been someone more appealing -- say, Alain Delon, instead of the somewhat weedy and overwrought Claude Rich -- would Je T'Aime be now regarded as a masterpiece? Quite possibly, yes.
For fans of Renais, worth seeking out. Otherwise, treat viewing Je T'aime as an experiment...from which you may or may not return.
