A very solid entry into the giant monster genre. What makes this stand out compared to most other kaiju flicks is the way that the human characters are actually likeable and entertaining to watch. Unlike many other kaiju films, the "plot-explaining" scenes here are not a nuisance that clutter the film and delay the giant monster fight scenes we're all waiting for. Instead they blend into the film well and feature characters that one can grow to like (Masako and Takuya's affectionate bickering was very amusing, for instance). It says a lot about the strength of the human characters when you consider that even the little girl featured in the cast is not a nuisance (though she does utter the hilarious line "I'll make my daddy get a -real- job!").
The actual city-stomping and monster-on-monster battle scenes are a delight as well, and there are plenty of them. While they're beginning to show their age, they still look polished and convincing enough to be entertaining, and are done with lots of style. Special mention must go to the beautiful music, which adds to the film greatly.
Of course, the main storyline is pretty daft, though stomachable. As usual with Mothra around, there's a rather thick environmentalist message to blurb out, but the subject's treated in a not too clunky fashion this time. There are the odd moments of cheesy special effects or clumsy dubbing, but nothing too serious. All in all this is a very entertaining film. It makes a good introduction to the genre for kaiju newbies and kaiju fanatics will lap it up. In fact, anyone with an interest whatsoever in modern Japanese culture shouldn't hesitate about checking this out.
That, and the chanting of "Mossura ya, Mossura..." tends to stick with one ^^.
