Parents need to know that "Hotel Transylvania 3: Summer Vacation" – the third film in the Hotel Transylvania series – follows Dracula (voiced by Adam Sandler) and his monster pals, including his half-human daughter, Mavis (Selena Gomez), and her family – on a luxury monster cruise vacation. There's a bit more scary stuff/violence here than in the previous films; much of it is comic, but there are some tense chases, crashes, and confrontations, a creepy robot/human hybrid, and a long sequence involving an enormous sea monster on a rampage. Expect a few mildly suggestive remarks and moments – butt jokes, buxom witches chasing after an elderly vampire in a skimpy bathing suit, etc. – and a few unflattering depictions of female characters, like a beautiful witch on a dating app who turns out to be a warty troll. There's also a fair bit of romance in the movie, but it's limited to flirting, dancing, and a couple of kisses. Positive messages include embracing diversity, letting go of negative feelings and grudges, believing in the power of love, parents and kids communicating with each other, and the importance of parents reconnecting as partners, not just co-parents.
