IMO, this is Toho's worst SPX film of all time, right behind REBIRTH OF MOTHRA II. It's actually gotten worse every time I've tried to watch it again.
I seriously doubt I'll ever bother watching it again in it's entirety, and most definitely won't bother buying a BD release. No amount of alcohol can make this movie any better.
If people dig it, that's fine; as long as they don't try to convince others it's some kind of underrated masterpiece.
