If you loved Sadako DX, try Fake
A bridge between a film you've already seen and one most people haven't. Fake has roughly 3.2× fewer votes than Sadako DX — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Theysit in Comedy / Horror / Mystery territory. If that's the register that drew you to Sadako DX, the second film will land in a comparable space — through a different lens.
What Fake is
Manhattan precinct. Winter. Sirens. NYPD detectives Dee and Ryo, partners in crime-solving and maybe something more, find their feelings tested when a trip to England turns into a baffling murder investigation. A tidy, if tonally-scattered, mid-90s anime curio for fans of procedural slash fiction.
