Verdict

The Sontaran Experiment is a down-to-Earth adventure where a group of humans struggle for survival as a monster hunts them down one-by-one. Entirely shot on location makes for an effectively realised story without the worry of limited and restricted studio space and time. The bleak Dartmoor makes for a perfect ravaged Earth and a dark glimpse into the future of mankind. There are good moments, visual effects and a cast who bring something new to the plot making for 45 minutes of slick and constructed entertainment. ****​
