In a series of mystery and horror these people will go through. When a man wakes up in a hole full of bodies and is terrified, especially since he does not remember anything about his identity, he quickly finds a house with five people who also suffer from memory loss. Their identity and the connection that binds them together and here the events begin.
The film's aura of mystery only works in the first 20 minutes or so, when it seems effortless; after that it feels like it's working very hard to keep the truth obscured, and in so doing just becomes a colorless slog.
Perhaps next time a little more faith in the power of visuals and performance would do the trick. Anything but another 100 minutes of dull characters sharing their inner monologue would be preferable.
Stock characters in a poorly plotted zombie-apocalypse storyline jabbed with a ham-fisted musical score, "Open Grave" is an elementary horror movie geared to set the genre back 30 years.
... another genre head-scratcher from López-Gallego, who last brought us 'Apollo 18' ... It won't impress the more literal-minded fans of 'World War Z' or 'The Crazies.'
Its climax may not be to everyone's tastes, but so relentless are the number of intriguing questions present in Open Grave's onset that it more than warrants a look.
The road to the finale is littered with dead bodies and red herrings, but Open Grave is more notable for its laid-back approach to storytelling than for its plot twists.
