DRIVEN TO EXTINCTION. BACK FOR REVENGE.
After being driven to extinction, great bloodthirsty dinosaurs come back to life with the assistance of a demented genetic scientist. She plans to replace the human race with a super-race of dinosaurs who will not pollute the planet.
That other dinosaur movie that was released in 1993, starring Laura Dern’s mom.
Just watched this recently. Pretty bad, but had it’s charms.
