If you loved Boy, try Cruel Story of Youth
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Nagisa Ōshima, and they both carry the outsider, raw mood tags, and they sit in Crime / Drama territory. If that's the register that drew you to Boy, the second film will land in a comparable space — through a different lens.

What Cruel Story of Youth is
Oshima's early film seeks to shock, and mostly succeeds. A young couple drifts into petty crime and nihilism in 1950s Japan. It got people talking, at least.
