A mystery train hurtling through space sounds like sci-fi setup, but this is Doraemon doing what it does best: taking a simple premise and folding genuine dread into it. The alien virus plot turns the confined space of the train into a slow-burn paranoia machine where nobody knows who's infected. It's the franchise's willingness to let the stakes feel real, even in a kids' movie, that makes the difference between a fun romp and something that actually sticks with you.

Nobita and his friends climb aboard a mystery train that travels through space, bound for a theme park out among the stars. Their trip goes wrong when a race of alien viruses attacks and tries to claim the kids as host bodies. The feature-length Doraemon film from 1996 blends outer space travel with fantasy adventure.
