Some stanley kubrick easter eggs In the movie, there is a Clockwork Orange book and a Frankie Goes to Hollywood mug, in one of the rooms
Both relate to Stanley Kubrick's, as the movie of the book was made by him and included a Frankie Goes to Hollywood song.
So as the movie was set in a hotel it has to be a nod to The Shining, they even have a creepy typewriter, so obviously, the writers are fans.
The story is different to the shining yet it's set in a creepy hotel, with lots of weird stuff going on I think the 6 stars is about right for this movie, It's worth watching if you have nothing to do.
