First, a disappointment: Megumi Odaka, the young woman with the very large ears who communicates with Godzilla telepathically, is NOT in this one...My children and I have dubbed her "Mickey Mouse" and enjoy seeing her in the series...
This movie has the BEST SPECIAL EFFECTS of ANY Godzilla movie that I have seen. The planes look like planes; the tanks look like tanks; and, Godzilla looks so COOL! He has gone through another make-over and has been given a cobra-like neck to go with the newer, smaller head and the glowing spinal plates.
Who else has a new look? The women that Dennis Miller refers to as the Mothra Chicks. New outfits, bare midriffs, ugly shoes...more contemporary ideals of beauty. And, they sing just as well as the originals...
The effects are most spectacular with Mothra, although I hear that Mothra is not really a moth, but a stunt butterfly in a moth-suit. The look of the giant insect is most realistic and the effects of his near miss flybys can almost be felt by the viewer.
Mechagodzilla looks pretty neat as well.
I won't give much of the plot away. There is less screen time for the child actors, but the movie is perfectly fine for children. No discernible death, just a lot of good clean monster fun...
