Good storyline, poorly paced.
I enjoy a good “thriller”, but I don’t think this movie was very thrilling whatsoever. Despite being a 1.5 hour movie, I felt like I had been watching it for 2+ hours. The entire story is shown from the perspective of Joe, the 911 operator, but this made the movie incredibly dull. The only thrilling aspect of this movie was waiting and waiting for the story to get interesting. When something finally does happen, you only get to hear it over the phone. I was bored while watching, but I wanted to know how the story ended. This movie had a lot more potential than what was used.
Watching this felt like a waste of time. The story was good, the execution was tedious.
