I'm beginning to find enjoyment out of all of Tezuka's films. The movies have a very Showa-ish feeling to them in terms of story. GXM's story is very run-of-the-mill, but when watching it recently I realized how many interesting techniques and camera movements were employed. The final fight also gets points for originality (Even if it is a bit goofy). GXMG is also has characters that really act as ciphers, but the story takes enough interesting twists and turns (Such as Mechagodzilla's rampage) that is doesn't matter. The fight is also, once again, very refreshing and well plotted out unlike most of the Heisei series (Or even Godzilla 2000 for that matter). Story-wise, GMMG suffers the most, seeing as its barely more than a remake of Mothra vs Godzilla. However, GMMG boasts the most impressive special effects in the whole series, and an amiable array of fight sequences.
Seriously, how can some of you guys whine about originality in Tezuka's films when we have the Heisei series? Tezuka actually mixes up his camera-work, and doesn't shoot everything through the bland static-camera. Besides, I'm willing to bet that Toho pushed him to use famous monsters like Mechagodzilla and Mothra after GxM bomed. Toho is a company after all, and it needs revenue. Personally, I still feel that all of Tezuka's films are better than Godzilla 2000 and Godzilla: Final Wars.
