this movie was shown a few times when I was growing up, usually on a Sunday afternoon. someone at good ol KWGN was definitely a fan of Universal monster movies. so while it's not the best giant bug on the loose movie, it's kind of a sentimental favorite. I mean, a giant mantis can be scary, but this one really doesn't do too much at all. the scariest is bit is actually at the end of the movie, and that was done just to startle the audience.
I wish I had better things to say about it.
