I have been watching Mystery Science Theater since it first appeared on Comedy Central so suffice it to say that I'm a sucker for a good bad movie. In the spirit of truly terrible films that involve sharks, I found another real gem under the same circumstances, in a Blockbuster.
A strong second in this category has to be Hammerhead. IMDB.com has this to say: “A scientist tries to save his son from cancer but his experiments turn him into a shark-man instead. A group of people from a pharmaceutical corporation are sent to the mad doctor's island to investigate his activities.”
When I did a Google image search for this one, and I recommend that you do the same, the images that filled my screen made me laugh so hard my roommates emerged from their rooms to see what all the noise was about. I don’t think it’s a “total terror” but is most definitely a total scream.
Okay, just one more. This one was recommended to be me by the Netflix algorithm. (As if they know me from my previous selections. Those silly equations don't know anything.)
It is total coincidence that all three of these movies have sea creatures in them. As I said at the start, I was watching an actual good movie and there are no monsters in that one. But there you have it folks, the power of synaptic misfiring and association.
