The Deadly Mantis
“This Was the Day That Engulfed the World in Terror!”
Certified Crap. CrapScore 47, rated by 1 admin.
Higher CrapScores mean more entertainingly bad. How we score movies.

A prehistoric mantis wakes up and takes an ambitious tour of North American infrastructure. The military briefings are plentiful, but some fog-shrouded creature work is surprisingly effective. Pick this for a patient retro-bug evening rather than a promise of continuous rubber-monster embarrassment.
