Let's see, this film terrified me in a good way, it was very intense and creepy. After, a cameo appearance from Meagan Good, we see many victims getting killed off, after they missed a call on thier phone. I thought it was excellent, because of the script and the directing. I thought it was stunning, because of the amazing visuals. I thought it was terrifying, because of the ringtone and of what's happening to these people. This will go down in my head, as one of the most creepiest and terrifying films, ever. I will definitely be buying this. Now, on to the movie. The acting, well I loved the acting. The two leads were awesome and were perfect for the roles. I was just so happy that this was better than what I expected. I highly recommend it and enjoy this for a fright!
