Like "The Terminator" in reverse, Mothra travels back in time to preemptively defeat a younger version of Godzilla's greatest foe, the evil three-headed King Ghidora, who we learn from Mothra's two diminutive priestesses that he's responsible for killing all of the dinosaurs and is now planning on killing the children of the world. So Mothra heads back in time to the "Land of the Lost" for kaiju-style fighting to stop Ghidora in a dinosaur-filled landscape. If you enjoy rubber-suited men pounding on each other on miniature sets, you'll very much enjoy this Mothra picture. It's nothing all the special, but for this type of film the special effects are solid, the story is serviceable, and and there was plenty of giant-monster-action. Here's to hoping Part 4 will revolve around Mothra having to get his parents to the Enchantment Under the Sea dance!
