A family’s beach vacation is interrupted by their violent doppelgangers.

There are twists and jumps and scares and blood spatter galore in this epic Jordan Peele horror/fantasy/sci-fi masterpiece. I saw echoes of and nods to classic terrors like “The Shining,” “A Clockwork Orange,” “The Strangers,” and even “Susperia” (in a beautifully choreographed and bloody dance battle). It goes off the rails, especially at the end, but in a good way, and manages to be both terrifying and hilarious. I think I need to watch it a few more times to fully digest everything going on in this movie.

If Toni Collette deserved an Oscar for “Hereditary” (and she did), then Lupita Nyong’o deserves them all for her dual roles in “Us.”
