I recall seeing this classic Japanese sci-fi movie on one of the local flea-pits(now long closed which is a shame). I found it very entertaining at the time. Years later, well 55 years later to be honest, I snapped up this copy because it was being sold at a good price and I was curious more than anything else since it had been such a long time since I had seen it.
I was not disappointed. Being a movie buff, I am easy to please, and being well aware of the times in which it was made, I knew the effects were no where near as good as they would be today. Nevertheless, the effects were very good for the times. The highlight of the movie for me was the appearance of the giant robot which set about flattening towns until being brought down by troops exploding a bridge. These scenes have to be seen to be believed! The rest of the movie is taken up with Japanese troops trying to destroy The Mysterians invasion of the earth, many scenes reminiscent of George Pal's version of War of The Worlds (still one of the best Sci-Fi's ever made in my view.) A very good entertaining movie, as long as you aren't too critical of the effects.
