Technically well made and historically significant, but not my cup of tea
21 May 2017 | by mevmijaumauSee all my reviews

I'm writing this review since no one else has done so yet (and there are almost no reviews of this movie elsewhere on the internet), which is a shame because I think Koji Wakamatsu's films are criminally under-seen. He's one of the most interesting directors of political and erotic films, so it sucks that he doesn't get talked about much outside of his native country.

This particular movie, Sex Jack, is not my favorite of his but is worth looking at. I'll be the first to say that I have no clue what the title is trying to say. Is the word "jack" used here meaning "a device for lifting heavy objects" or is it like in the words hijack, carjack, etc.? Either way, I'm baffled.

Anyway, the movie is about one of the favorite subjects of several Japanese directors of the '60s (Wakamatsu, Oshima, Adachi) - student demonstrations and revolutionary movements. More specifically, the film illustrates Wakamatsu's own disillusionment with such movements. His perspective is rather cynical, saying that he wanted to show how the revolutionary movements are always infiltrated by the moles working for the government. There is little hope for any sort of collective political struggle in this film. There's also probably a lot of subtext in this movie that flew over my head. It's definitely a product of its time, and you're not expected to watch it knowing nothing about it beforehand.

There's a lot to admire in Sex Jack. The atmosphere is very well done and easily transports you to the gloomy time period. The industrial, urban setting's ugliness is beautifully depicted and the B&W visuals in general are expressive. The climactic action sequence is fairly good. But overall, this movie failed to grab me. The plot is mind-numbingly repetitive. Watching naive student radicals repeatedly have sex with the girl in their group and have vague political discussions over and over doesn't quite fill the the runtime satisfyingly, even though the film is rather short. It features a lot of staples of Wakamatsu's work (politics, lots of sex, cynicism, some blood, the plot unfolding on very few locations and there being one or two sudden transitions to color), but it's not as emotionally resounding or poetic as in some of his other work.
