Though often considered a poor man's Tarantula (1955), I think that this flick has a lot of heart, and despite some of the failures in special effects (those webs look a lot like ropes, truth be told), I've always gotten a kick out of this film, no matter how many times I've seen it.
What did you think of this late 50's creature feature?
