...Jesus tap-dancing fucking tabarnak de câlisse de Christ.
If I come out of the theater swearing like that, it was either extremely bad, extremely good, or extremely memorable. The first and last rarely overlap; the last two, it's much more common.
The Monkey, directed by Osgood Perkins (who also made Longlegs, released last year) and released on February 21st, is a film adaptation of a short story by Stephen King first published in 1980 and then added to the Sketon Crew collection released in 1985. I talk a lot about games, movies and music on here, but I rarely mention how much of a reader I am - I got tons of books to get through, and Skeleton Crew is one of them. From what I've read about it, the stories in that one are particularly messed up, perhaps moreso than in other King short story collections I've read. Your... your life changes when you hear about Survivor Type. If you value your sanity, don't Google it.
Just in case you don't know what to expect from The Monkey, the tagline says enough: "Everybody dies, and that's fucked up". King himself loved it and described it as "batshit insane", so...
The story
Twin brothers Bill and Hal (both played during childhood by Christian Convery) grew up without their dad, a world traveler who up and left one day, leaving behind a treasure trove of souvenirs from his trips. The brothers have a strained relationship with each other, with Bill behaving very much like a bully to his younger brother. Digging through the souvenirs, the brothers find a blue round box containing an antique drum-banging monkey toy. "Turn the key and see what happens", says the box. Well, they do, and since nothing happens, they dismiss the thing as broken.
