Excellent if VERY repetitive.........
First the blu-ray quality is awesome on all three movies. All three movies are pretty moving, beautifully shot, and feature pretty excellent effects for 1966. Compare these movies' effects with the Gamera movies of the same era, Daimajin blows them all away!
The only problem is, they're all the same plot wise. It's like watching the original and it's two remakes, both filmed in the same year!
I still recommend them. I had never seen these movies before, shocking because I grew up watching all of the old horror/sci-fi flicks back in the 70s/80s on NYC television.
