Cast Joey King- Wren Julia Goldani Telles- Hallie Jaz Sinclair- Chloe Annalise Basso- Katie Alex Fitzalan- Tom Taylor Richardson- Lizzie Javier Botet- Slender Man A horror film that I watched on Netflix. Released by Sony. Legend has it that there is a supernatural being called the Slenderman. It can be summoned. However people will go missing. A group of young friends have heard about this lore and decide to take part. A week later things start to go wrong. A friend goes missing and they want to delve deeper into the mystery. Good special effects. Nice soundtrack. I will look at trivia and discussion.
