The worst time paradox/ time plot hole I have ever seen.
What were the writers thinking?
Let's see:
Future people come back and tell them of dire future.
They travel back to WWII and replace Godzillasaurs with 3 dorats and dump him in the ocean.
They go back through time back to 1991 and the prime minister says "So Godziller (that's how it sounds all the time on the crap dubbed version) is finally gone..." and everything still looks the same, except King Ghidorah flies into blow stuff up.
How the hell does everyone remember Godzilla when he was erased from time? And shouldn't all of history change, including the way the city looks? Seeing that they can rebuild the city of Tokyo in 2 years, who knows how developed that should have been if Godzill"er" never attacked?
Any then, suddenly Godzill"er" wakes up NOW, instead of earlier from nuclear waste (which a dumb cyborg w/ advanced technology from the future doesn't realize when he dumped him there) that happened to be sitting there. So the Japanese army decides to send a nuke sub on a suicide mission to wake him up, which he already was. But that is a dummy nitpick if anything.
Any other movie out there with a more messed up time paradox?
