To say Godzilla vs. Megaguirus is good for a while might be a stretch, but it’s definitely okay for a while. It’s a Godzilla movie with a lot of CG, whether it’s the giant monster itself swimming or the millions of prehistoric dragonflies out to sting him. Director Masaaki tries hard to integrate various effects styles, all with a certain degree of competence. This perceived competence makes it easier to endure the film’s lesser elements, like charmless lead Tanaka Misato.
Megaguirus takes itself–and its characters–way too seriously. Whether it’s Tanaka with her Ahab complex or Ibu Masatô’s politician with a secret, the film tries to give undesirable depth to its already unlikable cast. As the likable guy–the rogue computer programming with an inevitable crush on Tanka–Tanihara Shôsuke is actually sort of likable. Amid all the angst and seriousness, Tanihara seems like he’s at least enjoying being in a Godzilla movie. Him and one of the people running away from Godzilla later on. She doesn’t get a line, of course, but from her expression, you can tell she’s trying.
Then the bad guy, Megaguirus, shows up. It’s a giant bug. It’s a terrible design, terribly executed in the special effects, whether it’s the giant bug or how the giant bug flies around. Immediately upon its arrival, Masaaki’s built-up goodwill is gone. It just gets worse from then on, with terribly stylized fight scenes, bad mattes, ineptly constructed mattes, terrible music. For over halfway, Megaguirus is dumb but not incompetent, in fact it appears like it might be downright ambitious in creating a 21st century Godzilla.
But it isn’t. It’s a lame wreck of a film. It doesn’t help Tanaka manages to get more annoying in the finale. It probably doesn’t hurt much–after Tanihara’s inexplicable striptease of silly bandages, nothing could bring Megaguirus back from the brink.
