Good Boy, a new scary movie told entirely from a dog's POV, just premiered at South by Southwest Festival in Austin, Texas – and it's already being called "one of the best horror films of the year".

What could have easily been a cheap gimmick instead provides the foundation for one of the best horror films so far this year.

Good Boy drops audiences into this scary terrain, centering its haunted house story on a dedicated dog who is desperately trying to warn his human bestie about the supernatural threats closing in. Focusing on a dog in danger is a bold move.

Good Boy, about a dog protecting its owner from ghosts only he can see, is a fun genre exercise that stretches its premise to its logical limits.

Premiering at SXSW, Ben Leonberg's ghost story unfolds entirely from a dog's perspective.
