"Sontarans and South Africans",
This review is from: Doctor Who - The Sontaran Experiment  [DVD]  (DVD)
A good 2 parter shot entirely on location, Dartmoor adding more than a little atmosphere.
Yes, the script is a bit scatalogical. We can accept the experiments are all testing the mortality of Humans, but given there's so few on the planet, why bother? I reckon Styre's just making snuff videos for the Marshall!
Great characterisation for the Sontarans, easily the best non-Robert Holmes Sontaran script-so far! Kevin Lindsay's performance takes full advantage of lines like (on reacting to a scream) "Why did you make that disagreeable noise?" and calling the Doctor a "maggot"!
The Doctor/Sarah/Harry triumvirate is working well here, 3 never seems like a crowd. Sarah becomes a torture victim largely relying on camera angles and Elisabeth Sladen's strong performance, Harry switches from credible doctor (he knows someone deprived of water should be given a small amount and not a cupfull) to someone who can fall down a "whacking great subsidence" and then resolve to teach a murderous Sontaran a lesson without ever seeming a buffoon.
Uncle Tom plays the action man here falling down the same subsidence and challenging the Sontaran to a duel. The sequence where he declares "I'm the Warrior Class!" is a joy!
The colonists are not so memorable although it's good they're not speaking in received pronunciation, even if the South African accent is so easily identifiable.
A good functional design for the robot.
"Built for War" covers the 4 Sontaran stories, focussing mainly on the 1st 2, utilising Lis Sladen but also featuring soundbites from Colin Baker, Nicola Bryant & others. Great stuff.
Of course there's a commentary (sadly not a Tommentary) which stars Ms Sladen and covers memories of the location, Kevin Lindsay's lunch being sent up the hill on a tray and Tom's snapped collar bone.
A great start for the budget DVDs with better extras than some of the full price ones (yes "Claws of Axos", I am talking about you!).
Recommended for all.
