The Monster That Challenged the World

“A new kind of terror to numb the nerves!”

Certified Crap. CrapScore 51, rated by 1 admin.

Higher CrapScores mean more entertainingly bad. How we score movies.

Why it’s crap
An earthquake releases giant molluscs, and the authorities discover that even a very large shellfish can cause a complicated working week. This earnest creature feature balances investigation with a satisfyingly tangible monster. Bring an appreciation for fifties science and substantial practical props.
