Underwater parents guide

What we could confirm fits a PG-13: real scares and several jump scares.

Scare: Properly scary; Frightening, not just tense.
Jump scares: Several; More than a couple of sudden jolts.
Gore: Light gore; Some blood or injury, briefly.
Violence: Strong violence; Violence is frequent or intense.
Sex and nudity: None flagged; It is a horror title, so treat our zero as unconfirmed.
Language: Moderate; Some strong profanity, a few f-words.

How we rate: an AI reads what is known about each title and tags it 0 to 3; we check the tags against a hand-rated set and correct them by hand when readers tell us. Estimates, not a scene-by-scene review. Spot a mistake? Tell us.
