Yeah those parts of Shinsei really fell flat to me. G2000 had the same idea in the plot as well. It just kept bumming me out and I simply couldn't buy the MC's seething hatred for a creature that was clearly not malevolent, like GMK and Shin. People don't come to a godzilla movie to root against godzilla; he's too ingrained in the public consciousness as a "force of nature" that defends just as much as he destroys. To make people root against him, you have to immediately show that your movie's godzilla is different from the godzilla "you know".



To bring up the old Godzilla Neo terminology, Shin is Godzilla re-imagined as a class 3 with Destroyah's origin, weakness, and overall ability set.



Heisei had this to an extent but it was rarely in the forefront. I think Japan has finally figured out how to do "evil godzilla" though with Shin. I like that Legendary and Toho can have these two simultaneous wildly different takes on the charachter, it really is the best of both worlds now.
