OK, I have actually heard this Hammer film described in the summary line I gave this comment. This was the first Hammer film I ever saw, although I was 6 or 7 at the time, so I had no clue who put out this little gem. My cousins and I watched it on late-night TV on Thanksgiving night and we sat there, mouths wide open and totally entranced in what was going on in the film. Sure, this isn't the best film ever released by Hammer Studios, but I'll go to my grave fighting that while it may not be a classic in the usual terms, it is most entertaining.
How can you not enjoy man-eating seaweed, descendants of the Spanish Inquistion, the strangest sea-beasties you've ever laid eyes on and an opening tune that you can't get out of your head, days after viewing it! While this isn't a film I'd recommend to most classic fantasy film fans or even Hammer film fans to go out and purchase, blindly, I would recommend at least giving it a view, it certainly isn't a kind of film where you'll want to pluck your eyes out, after viewing and who knows, if you watch it in the right frame of mind, you may end up enjoying it.
