I've always enjoyed this film that turned out to be Jack Arnolds last horror film and I really do not understand why some people think this is awful. There are some flicks that you don't have to take seriously and all you have to do is sit back and have fun watching. Sure, its silly but most 50's sci-fi is. Why is this worse than others? The music that is used is from other Arnold films most notably "Tarantula" and I'm sure Universal used the same score for countless other movies. A lot of Arnold regulars pop up like Whit Bissell, Phil Harvey, Ross Elliott, Richard Cutting and of course Mr. Ziffel, Hank Patterson! Eddie Parker plays the monster here in make-up, not Arthur Franz and Parker was also in "Tarantula" in two roles. Both as lab assistance who die of that deforming disease. Troy Donahue in one of his early roles is Jimmy and he's especially wooden. But Arnold knows exactly how to tell a story no matter how silly and the scene with the giant dragonfly is fun, so is the whole movie.
