If you loved Xtro, try Dr. Caligari
A bridge between a film you've already seen and one most people haven't. Dr. Caligari has roughly 3.7× fewer votes than Xtro — 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 Horror / Science Fiction territory. If that's the register that drew you to Xtro, the second film will land in a comparable space — through a different lens.
What Dr. Caligari is
Basement lab, winter, the hum of a warped gramophone. A doctor in a silk mask adjusts a dial on a writhing, leather-bound machine shaped like a spine. Less Cronenberg, more boudoir grotesque—bring your own leather gloves.
