Even though I watch a lot of bad movies, it's been awhile since I've seen a plot that made less sense than the one found in Blood Waters of Dr. Z. For reasons known only to him, Dr. Kurt Leopold decides the planet would be a better place if fish were to take over. After a rather lengthy voice-over soliloquy on the subject, he dunks himself into a tank and comes out transformed into some sort of poorly designed would-be fish-creature. With his handy spray bottle filled with I'm not sure what, he sets out on his mission to lead the catfish in a takeover of the Earth. Before you can say "carp", Dr. Leopold's plan seems to be forgotten in favor of finding a mate he can transform into a would-be fish-creature. (Actually, I'm of the opinion that getting laid was Dr. Leopold's goal the whole time. Forget about the nonsense of a master race of fish.) As the bodies start to pile up, old fish-boy soon has some scientists and the local sheriff on his tail. Can they put a stop to Dr. Leopold and his plans for world domination?
Whether you call the movie Blood Waters of Dr. Z or Zaat or ZaAt or Attack of the Swamp Creatures, it really doesn't matter. Crap by any name is still crap. The movie is Grade A bottom-of-the-barrel film-making. As I pointed out, the plot is ridiculous. The technical aspects of the films like lighting, sound, special effects, editing, etc. are beyond bad. The direction is amateurish at best. And as for the acting, I'm not in the least surprised to discover that no one involved ever did anything other than appear in this monstrosity (okay, one guy does have one other credit, but that's it). Quite honestly, my rating of a 2/10 is incredibly generous. I'm sure there's a reason I didn't give Blood Waters of Dr. Z the dreaded 1/10, but sitting here 12 hours after watching the movie, I can't come up with a valid explanation.
One of the comments on IMDb bemoans the fact that the majority of people rating and reviewing Blood Waters of Dr. Z have only seen the Mystery Science Theater 3000 version (that's how I saw it also). The comment states that the real movie has 30 or so minutes edited out by the MST3K crew and the movie shouldn't be judged unless someone has seen the whole thing. Well why in God's name would I want to see 30 more minutes of this trash! The time I've already devoted to Blood Waters of Dr. Z is above and beyond what it deserves. Just be glad more people haven't seen that additional footage as I'm guessing the rating would be even lower if they had.
