Mark A.Z. Dippé directs with a fair competence. The film has been economically contrived so that almost all of it takes place around three houseboats in a single lagoon. The Frankenfish effects, which are done on the cheap by a South Korean CGI house, are competent and there is a fair array of splattery gore effects throughout. In fact, Frankenfish feels like it was made around the era of one of the cheerfully tongue-in-cheek copies of Jaws (1975) from New World Pictures such as Piranha (1978), Up from the Depths (1979), Alligator (1980) and Humanoids from the Deep (1980). Frequently, Dippé plants his tongue in cheek like the scene where Raoul Trujillo kills a Frankenfish and then promptly rips its heart out and throws it on a barbeque. And then there is the entertaining climax where Tory Kittles and K.D. Aubert contrive to get the fish to jump into the fan of a swamp boat and he consoles her afterwards: You look great for a girl covered in giant fish brain. Dippé also takes frequent opportunity throughout to toss in wholly gratuitous sequences with big-breasted women parading about topless.
While Frankenfish progresses in standard ways for the better part, there are times it takes detours that leave one curling their eyebrows like where hero Tory Kittles and biologist assistant China Chow sit down to have dinner with Donna Biscoe, daughter K.D. Aubert and K.D.s lawyer boyfriend Mathew Rauch where it is suddenly revealed that Kittles is the lost high school crush of Aubert who began cheerleading just to be near him on the football team; how Aubert exits to the houseboat veranda after an argument with Rauch where Chow joins her and commiserates by suggesting she try a woman instead of a man; and Aubert then returns to the dinner table to find that her mother has fed Kittles a cup of voodoo tea to spur along their attraction. The victimology is not always predictable China Chow seems set to be the female lead but is then bumped off two-thirds of the way through; Mathew Rauch is set up to be the asshole lawyer who has victim tattooed to his forehead but is spared up until the very end while far more likeable cast members end up being bumped off.
Lead actor Tory Kittles gives a strong and assured performance. More to the point, he plays the part with complete seriousness, which is way and above what the material requires. On the other hand, China Chow, who is initially paired as the lead actress opposite him, makes little distinction.
