I enjoyed this movie a great deal. Was hooked right from the opening moments (which was extremely well acted), they do a good job making a simple premise work well and be interesting. It does a fantastic job filling you with dread pretty much the entire way through and being worried about what happens next. For sure my favourite aspect about it, I like when horror is able to make me feel extremely unsettled and paranoid. Acting wise, I thought Sosie Bacon was really solid in the lead role, but I thought some of the other cast were a bit hit or miss. Nothing that took me out of the movie, but quite a mixed bag I thought. Some great, some felt not very natural. I was really impressed by Caitlin Stasey the most, her character leaves a lasting impression on you and the visual especially, it sets the tone for the rest of the movie up really well. Speaking of visuals, some very effective ones in this that definitely disturb you. All in all, a great movie worth your time that is paced well and does a stellar job keeping you entertained.
