Marshall Thompson, along with Kenneth Tobey and Richard Carson are my favorite 50’s sci-fi leads that was one of the big pluses of this movie. On the other hand it seemed rushed and too short. The love interest, which I normally like in Sci-Fi’s was a bit distracting. The blossoming relationship developed very unevenly, flip-flopping twice – initially they are immediately attracted to each other then she (wrongly)gets so mad that she doesn’t want to see him again, then suddenly for no reason they are in love again. This was just another aspect of the general rushed feeling of the movie and the movie could have been a good 15 minutes longer. There were a number of missed opportunities where there could have been more action scenes – ie.wide spread panic in the town and even some more kinetic rushing around with jeeps going air borne in a rush to save the day! Lots of times people get attacked but just stand around staring when they should have been running or picking up something to kill these extremely vulnerable creatures. There were a number of scenes that could have used more actors such as the power plant(which was shown as being huge) that had only one person working there! The stop motion effects and the female lead’s tight fitting, stretched to the limit sweater were the highlights of the movie, the low was the female lead’s distracting receding hairline, even her bangs couldn’t hide it. The main actors were good but some of the second leads were awfully wooden. My DVD was put out by Criterion and was pretty good quality except for the scenes in the woods; they were quite dark but fixable with the VLC’s on the fly video editing features. Not a great B movie but not a bad one either.
