30 May 2005 | by horrorfilmxSee all my reviews

I recently (and reluctantly) posted a somewhat negative review of the Mexican classic BRAINIAC. Last night I watched DOCTOR OF DOOM and my faith has been restored! This is the kind of goofy fun I expect from old south of the border exploitation films. A mad scientist kidnaps women for brain transplant experiments! His henchman is a hulking guy with a gorilla brain in his skull! The detectives are trapped in one of those rooms with spiked walls that close in on you! Wrestling women who look like Laura Petrie on steroids save the day! Oh man, it doesn't get better than this. I especially liked the detective captain's sidekick, a little guy one of the women refers to as a "five foot lightning bolt." He's actually funny and engaging. At one point he faces nearly certain doom and radios his girl friend for help. If she doesn't hurry, he says, they'll never walk down the aisle together. "Don't talk like that, small hero!" she responds, "I'll be there like white lightning!" I felt like I'd been drinking white lightning while I watched this. Check it out!
