I was critical of this film at first due to the bones of the original Godzilla being used to create MechaG, it was a great concept and fresh new twist on MechaG and explains why someone would build a robot in Godzilla's image since they had to work around its skeleton, but I was pretty certain the bones had been disintegrated along with the rest of him at the end of the first Goji film.
HOWEVER, once ya get past that, or if you're able to ignore that and accept that in THIS continuity the bones somehow survived afterall, then its easier to fully enjoy.
Plus, I like the redesigned Millennium Goji suit, he still has the same feral, spiny reptilian look from Godzilla 2000 and Godzilla vs Megaguirus, BUT, his scales and bones have been returned to their original coloration.
I actually prefer his trademark blue atomic breath better, looks more exotic and impressive than regular colored flame. However, I do love his Heisei era spiral atomic breath as a finishing, super powered move
The spiral atomic breath was stronger (love that finishing move, glad they brought it back in Final Wars), but the red and orange flame seen in Godzilla 2000 & Godzilla vs Megaguirus was the same power level as the blue flame, just recolored for some reason
Its judt that i like the red-orange one better. Everyone has their own preferences after all. And speaking on the spiral one, it was used in 1995. Although Godzilla VS Destroyah was awsome, god did it make me cry.
