This movie starts off as a family vacation at a resort in a tropical location. Cancun is mentioned but it doesn't say this is in Mexico. I take it to be any place we all dream about escaping to on a "real vacation". The movie takes a turn when some of the characters are invited for the day to a secluded Beach in a nature preserve. Look for The Cameo of M Night Shyamalan as well. No spoilers but this movie mskes you think. The main themes are aging, dying, death snd family.
