Could be seen as a cautionary tale about leaving well enough alone -- i.e. "curiosity killed the cat."
Positive Role Models & Representations
Frequent, loud fantasy/monster violence, with a few blood spatters. Neck slicing. Stabbing with knives, spears, and darts. Guns and shooting. Explosions. A flock of birds smashes through the front of a plane. Plane crash (not shown), car crash. Some jump-scares. Scary faces, relentless zombie attacks. A lab full of skeletons and other gross things.
Male-and-female sensuality. Kissing. Lovers shown in bed together. No nudity seen, but it's implied in several scenes. A mostly-obscured naked bottom. A man is naked, but nothing is seen beyond his torso and legs. Subtle, suggestive sex talk. A man stares at a woman's belly button. Brief flirting.
A use of "s--t" and "a--hole." A use of "son of a bitch" (partly obscured by noise), plus "hell," "damn," and "oh my god" as an exclamation.
Nothing in the movie, but part of a larger franchise with some associated merchandising/licensing.
Ease of Play
The main character quickly downs several glasses of liquor in more than one scene, with no effect/impact or consequence.
