watched this by accident instead of creep (2014)

I saw this girl i really like on YouTube had done a review of a movie called creep and the title was 'creep 2014 review - possibly the best movie I've seen all year' or something like that, and because I didn't want anything to get spoiled i didn't watch the review but I knew we had similar tastes so I went to blockbuster and got the only film I saw called creep and didn't realise until the end when I googled it trying to find the plot (because this confused me) that Id watched the complete wrong film lmao,
