Just awful, awful writing, and a bevy of hollow characters. The movie opens with a definition of rabies, referring to it as hydrophobia, but then it completely fails to depict what rabies actually does to infected animals.

Why even mention the rabies if it's not consequential to the story? I was just left wondering why the hell not a single person ever splashes pool water at this asshole. Like, not even one little knee-jerk "AH!" type of inadvertent splash to confirm he's scared of water?

Why wouldn't they just stay in the pool until the handler comes back? And why did nobody ever turn on any lights? If there's a monkey stalking around a house in the dark, the first thing any sane person does is scream, "Alexa, turn lights on!"

This movie sucked.
