I agree that its the weakest of the 3. However, I like that movie more than I like the two millennium ones(godzilla against mechagodzilla and tokyo s.o.s) And Im putting my love for the Heisei series aside, Its just a litte more entertaining.
Nothing beats the Showa series Mechagodzilla, though. He has maybe the best design in all of the Showa series period. Hes a p.o.s. too, a villian in the truest sense. What he does to Anguirus is Unforgivable!!!!!! lol, my problem with him, is not him personally though, just the company he keeps. King Ceaser and Titanosaurus. (SIGH) It seems when Mecha G is around, its an open door for the bums to come play in the sandbox. Too a lesser extent Rodan in the G vs. Mecha G II.
