If you loved For Love's Sake, try Dead or Alive 2: Birds
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 Takashi Miike, and they both carry the bittersweet mood tag, and they sit in Comedy / Drama territory. If that's the register that drew you to For Love's Sake, the second film will land in a comparable space — through a different lens.
What Dead or Alive 2: Birds is
Takashi Miike seemingly asked himself, "What if two hitmen had feelings?" Childhood friends Ryuichi and Shuichi rediscover their bond during a job. They briefly retire to their hometown to contemplate their lives before deciding to become vigilantes. It's probably the most heartfelt movie about contract killers you'll ever see.
