this movie start by show you a map and then explain radar and it be quite awhile before you ever see the deadly mantis . probably a good movie in the 50 this dated piece be a bit to slow moving and the pay off in the end isn not very good . though it have it moment like when the guy from perry mason argue with an old man and when he say i have narrow the possibility to one excuse me and but when you narrow something down you have a couple or more possibility not one . if you get it down to one you haven not narrow it down and but you have in fact figure out what it be . the monster be standard 50 sci fi fair and good than say the grasshopper in the beginning of the end . acting be sub par and the heroine be the most unattractive . in fact in some shot she do look like a guy in drag . you see plenty of fighter plane stock footage and other thing and but you would not see much at all of the deadly mantis .
