"Raising the bar is the perfect way to ruin the spirit of a Godzilla movie."
Oh, I couldn't agree with you more. My comment was only that most in the series were so bad, that making the "best Godzilla movie" isn't much of a stretch...
I grew up watching cheap sci-fi/monster movies. If they weren't hysterically-funny, they'd be unwatchable. You can't take something that was unintentionally funny and make a new, serious, "hi-tech" version that people will want to see. Look at "Lost in Space: The Movie". Bad idea, bad movie.
A goodly portion of my misspent youth was wiled away at drive-ins watching Toho films. In their quest for the absolute bottom of horrible sci-fi films I would have to nominate "The Green Slime".
