I usually love not very good Sci-Fi films from the 1950s but this effort was an exception to that. I could only bear to watch about ten minutes at a time but I was determined to get to the end, which I did eventually.
Poor in every way which can sometimes be entertaining but not with this film. The baddie looked like a kindly grandpa and was not in the least threatening. Bad acting all round and even in 1956 this was probably not seen as being a good film, even if it was cobbled together from a TV series of the time.
It's worth watching to see how bad a 1950's Sci-Fi effort can be but it's a struggle to get to the end as it's so bad.
