It's fun, it's light, [but] it has a hard time when its tries to get heavy.

Easily the biggest piece of Right wing non sense propaganda I ever saw.

The film may be flawed, but its message is not.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

Unlike some of the other Italian rip-off shark movies I've seen, this one is not all stock footage. It does steel footage from The Last Shark, but it also has its own mechanical shark and its own live shark footage. The movie's story has its sad moments, and that's part of a good film to me. The music is pretty bad, though. There are a couple good sounding themes in there but other than that, it's bad movie music. This isn't really a Jaws rip-off, more of a knock-off of The Last Shark since it has stock footage from it. In this movie, there is a wise old Indian who is very well acted and plays a very good role in the story. Other than the music, it's a good movie.

Just when you finally, absolutely, positively thought it was safe to go back into the water, up pops yet another Italian Jaws rip off—and slap me with a dorsal fin and chew my legs off if this isn't one of the most tedious of them all.Directed by Raffaele Donato (with more than a bit of uncredited help from the king of Italian sleaze Joe D'amato), Deep Blood is a virtually joyless experience from start to finish, with a dreary plot, umpteen characters that are indistinguishable from one another, terrible acting (nearly all the performers fumble their lines at least once), and unconvincing shark attack scenes comprising of various odds and ends of stock footage badly inter-cut with the frenzied thrashing of the supposed victims.The dreadful script offers a few unintentionally hilarious scenes, such as the sight of the film's heroes nipping to the local dynamite depot to stock up with enough high explosives to sink a battleship, or the hasty construction of a special shark attracting device that consists of a metal box with a flashing light on top, and further giggles might be had from the witnesses to the shark attacks, who run the gamut of emotions from 'mildy concerned' to 'slightly perturbed'; to be honest though, these brief moments of levity do little to compensate viewers for suffering through the rest of this bloody awful film.

This is the worst italian movie ever, quite possibly the worst movie of all time! Joe D'Amato is of course no cinematic genius but many of his movies are interesting and watchable. Unfortunatly this is not one of them. Its cheesy and boring....waaaaay boring. If you want a movie to MST3k, get Troll 2, if you want a movie to put someone into a coma, get deep blood!

I like to think of myself as a bad movie connoisseur. I like to think that the films most people label as the worst of all time I can easily withstand.But...there are exceptions. I can only recall three movies I have had the misfortune to see that I have repeatedly used the fast-forward button for large chunks of the story. Those movies are The Mighty Gorga, Night of the Seagulls, and this little crap, Deep Blood.In the world of Jaws ripoffs, this falls off the scale. Deep Blood doesn't have the realistic storyline of the original Crocodile, nor the incredible effects of The Sea Serpent, nor the commentary of Tintorera. No, instead we are treated to a handful of teens from any random failed '80s public access sitcom battling bullies and the local sheriff.Shark attacks are realized by quick cuts of documentary footage with actors thrashing about in the water, occasionally with a bit of what appears to be orange-ish paint thrown into the water. Not a minute of original shark footage exists in this celluloid waste dump.Normally, I, or somebody like me, would read a dismal review like this one and say "cool, I gotta find a copy of this!" That's the same thought I had when I read another viewer's review on this very site. How wrong I was.So...from one bad movie fan to another...let this collect dust on the shelf...grab Up From the Depths or The Great Alligator instead to satisfy your need for something evil lurking in the water.
