I can't decide which is worse, 1991's Godzilla vs King Ghidorah or 1971's Godzilla vs Hedorah?
On the one hand you have a time travel plot that made NO sense no matter how much disbelief you suspended and a King Ghidorah origin story that made even less sense. On the other, you have Godzilla flying with his breath, in a storyline that could only make sense if it was actually a nightmare Ichiro was having after eating 10 lbs of candy for dinner (again).
