He's gone from villian to hero to anti-hero in the past:Guess the movie I was thinking of was 1998.
Is Godzilla A Hero Or Villain? Why It's So Confusing
Godzilla as a force of good is so out of wack. Anti-hero makes sense but these movies have people that worship Godzilla. "Sure he may be killing millions, but it's your fault you made him angry!"
Kong movies imo do a much better job making you care for him, even if it's the same "don't mess with nature" theme.
