Last night my wife and I watched The Land that Time Forgot--a movie that you should forget about.
The movie starts off (merely) bad, as we see a band of survivors from a sunken WWII merchant vessel, through luck and daring, capture the u-boat that sunk their vessel. The wily nazis manage to trick their captors into steering the vessel deep into the south atlantic, at which point they reveal their hidden arms and reimprison the survivors (except, of course, for the sexy blond microbiologist survivor). The survivors-turned-captors-turned-captives (via the blond babe) turn the tables once more and destroy the nazi supply ship with which the u-boat was to rendezvous.
Then, it gets worse.
It has an incomprehensible plot, gratuitous violence (let's kill the cute dinosaurs just for fun!), implausibility heaped upon impossibility, really bad dinosaur props, and gobs of pseudoscience, pseudomorality, pseudosexuality, pseudoengineering, pseudoevil, pseudovirtue, etc.
No Pseudoerasmus, though. Even the smartest characters in this movie are stupid.
Watch this movie at your peril.
