Downtime. I like it. Oh it's flawed, mainly because of the uber-low budget (the Yeti look really crap) but it's a decent story and has a nice lead performance from Nicholas Courtney. It's nice to see Lis Sladen and Deborah Watling (God, all the classic leads in this are dead) and I still vastly, vastly prefer Beverly Cressman's Kate to the block of wood we got in New Who...
