Premise could work as a comedy short, but stretched out to a toothless, clawless, 93 minutes it's excruciating.
This single note, inoffensive, meme comedy is way too bland for my tastes. All the kills are off screen. Sans sloth puppet there's no sfx. Kills are of the lame 'blood splatters on wall' variety.
Maybe it fits the bill for tween girls at a sleepover?
This is NOT the Piranha 3d of killer sloth movies
