Some bad movies are so bad they're unwatchable, but I stumbled upon a hidden gem tonight when I found Frankenstein Meets The Space Monster.
It's worth watching and I found it quite entertaining. There are lots of cool shots of the area around mid-60's Cape Kennedy and Puerto Rico along with stock footage of a lineup of Century-Class fighters in action and an Army air assault operation utilizing Sikorsky H-34's.
One of the villains, Captain Nadir, looks like Nosferatu after he became engaged in the BDSM lifestyle. The "space monster" looks like one of the members of Virginia-based rock band GWAR and after "frankenstein" gets half his face burned off (he's half "robut," as they pronounce it) it's obvious that the "circuitry" on the side of his head is comprised of old transistor radio turning dials and a a wristwatch movement glued to his head.
It's got a pretty hip (for the day) soundtrack and lots of good special effects noises. Of course, it wouldn't be complete without lots of girls in bikinis.
I thought one of the Martians looked familiar but couldn't quite put my finger on his identity but I found out later it was Bruce Clover, father of oddball actor Crispin Glover.
Well worth watching in my opinion. Available free on Prime Video and, of course, YouTube.
