Back when I was a kid, I loved it. It was fun as all get-out. Even though I was limited to a yellow-tinted VHS tape, it still appealed to me. The AIP dub was one of the best dubbing jobs ever done for a Godzilla movie, in my opinion.
Ever since I got the Sony DVD, seeing it uncut, with it's original Japanese dialogue, and in a glorious-quality widescreen print, I fell in love with it all over again. Critically, I'd say it's definitely Fukuda's best Godzilla movie. Entertainment-wise, it remains one of my favorite Godzilla movies to this day, tied with Godzilla vs. Mechagodzilla as my favorite Showa Godzilla movie.
