Yeah, I've been thinking of that film. I think I'll finally watch my Criterion BD of it this upcoming holiday weekend.
Yep. The Criterion BD is the one I watched. I watched the Japanese version twice: with and with out the commentary. I don't listen to commentary tracks very often, but I will recommend the track on the Criterion. I was only going to sample it in order to see what it was like and ended up listening to the whole track. The Godzilla film historian doing the commentary managed to keep it pretty interesting.
