…a fairly typical example of the Roger Corman ethos in action…both sections of the film are well-done, even if there’s not much connection in terms of story or theme…

Despite the regular violence, the scaly creature costumes (which are rather comical when revealed in broad daylight), the mad scientist, and the otherworldly voodoo, the film isn’t creative enough to hold much interest.

I can't vouch for the edited U.S. version known as Screamers, but the Italian original Island of the Fishmen is low-rent fun.

Genre addicts might feel a little let down by the picture's eventual restraint, but what the feature lacks in sustained aggression, it makes up for in tolerable escapism.
