If you loved Pan's Labyrinth, try Frankenstein
A bridge between a film you've already seen and one most people haven't. Frankenstein has roughly 3.4× fewer votes than Pan's Labyrinth — 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

What Frankenstein is
A dimly lit laboratory, stormy night, a spark of electricity. A scientist's hubris and a creature's first stumble, an experiment gone awry. Del Toro's visual flair elevates this classic tale.
