There were only two 6th Doctor (Colin Baker) episodes I thought were worth the paper the scripts were written on and this was one of them. Now I'm not saying this was a classic episode. But it was one of the best acted episodes of the Colin Baker period, the special effects were decent for the period and the monster/villain was well-realized. For those who are selective in their purchases of Dr. Who videos, this is one worth the money. The only other Colin Baker episode worth the money for selective buyers is Vengeance on Varos. The others are for hard core fans to complete their libraries!
