Query: Scarey and shocking

I was planning on eating while watching this movie. After 15 to 20 minutes that thought was gone. It was shocking scary and everything I thought a movie like this should be. I started writing this review while watching it thinking this was a good thriller/horror film. I liked it a lot ready to give it 4 stars until the movie just ended without any conclusion like it just stopped. The film ended unfinished in my opinion all they needed was like 5 minutes to give it an ending. Basically in the end when you are expecting everyone to be caught or get away who lives or dies the screen went black 15 seconds later the words start coming. The movies was over.
