Barbarian is a great horror movie, both in style and writing. It captures the viewer right from the beginning with a cinematography that manages to subtly portray the house as creepy in one scene and cozy in the next. The whole presentation is masterfully done and abruptly shifts multiple times throughout the story.
The actors, and Georgina Campbell in particular, are consistently great. This is one of those movies that manages to become scarier by "tricking" smart and in part relatable characters into helpless and intense situations instead of relying on slasher cliches. Barbarian really keeps you on your toes with unexpected twists and only the final quarter includes a number of regular horror movie tropes.
Overall great writing, cast and characters. The movie is scary, exciting, gross, disturbing and even a bit funny at times. I can highly recommended this to any fans of the genre.
