Commandos and teenagers versus pterodactyls!
You don't tune into a movie called Pterodactyl expecting it to reshape your notion of high cinema - you tune in hoping to see a well-made creature feature! And in this regard, Pterodactyl is a guilty pleasure indeed.
Many of the characters are named after famous science-fiction and fantasy writers - Burroughs (Edgar Rice Burroughs), Clarke (Sir Arthur C. Clarke),Donaldson (Steven Donaldson), Heinlein (Robert A. Heinlein), Herbert (Frank Herbert, Brian Herbert), Lem (Stanislaw Lem), Lovecraft (H.P. Lovecraft), Serling (Rod Serling), Yolen (Jane Yolen) and Zelazny (Roger Zelazny).
Mark Lester also directed Commando and Firestarter.
Should you watch it if you tend to like these kinds of movies? Does it deliver the requisite gore, thrills, explosions and unrelenting gunfire you'd hope from a creature feature? Hell yes!
