Incidentally, my hubby and I watched the TV show of the same name last night -- mostly entirely by accident. My professional opinion? One day, in the not-too-distant future, Tom Servo, Crow T. Robot, and the rest of the Mystery Science Theater 3000 gang will eat it for lunch. Terrible!
Rule #1: If your entire special effects budget is $37.50, you probably shouldn't base your show on malicious lizards that are either the size of Germany or your grandmother's cat (a bit difficult to tell).
Rule #2: Planet-swallowing tidal waves lose their dramatic appeal if you don't show them.
