Godzilla vs. Megaguirus (2000) features the Japanese in a guise which desires not to be victims, but exterminators of the great lizard. They’ve concocted a weapon which spits black holes, but after its first test run, ancient flying creatures named Meganula appear (think 10 ft long dragonflies), plucking up juicy morsels to eat and eventually flooding Tokyo, probably because their molted skins clogged a sewer drain.
Meanwhile, Godzilla is on his way towards Tokyo, for reasons unknown – which give the Japanese a chance to eliminate him. But their attempt fails, and while waiting for the weapon to recharge, the Meganula arrive. The Japanese haven’t been able to do much with them, but Godzilla’s advanced halitosis weapon proves effective, and the battered Meganula survivors return to flooded Tokyo, where they fire up their mother / father / avenging god, Megaguirus. Yep, a giant dragonfly.
While the humans flit about ineffectively, Godzilla and Megaguirus have a traditional monster grudge match, and after a setback or three, Godzilla manages to burn Megaguirus to a crisp. At this point, the satellite housing the black hole gun is caught in a decaying orbit, and they only just manage to fire it at Godzilla, who then disappears. Some big wig goes to jail for concealing a banned plasma energy research facility in Tokyo, which is what attracted Godzilla to same.
And, speaking of, is he really gone?
Packed full of the usual ineffectual Japanese characters, the high point of this film is Godzilla himself, who looks suitably crabby about the entire thing. Megaguirus, on the other hand, is just a boring plastic model, and the Meganula aren’t much better.
Yeah, don’t bother, unless you’re a completist. Then do it with a case of beer.
