S2 Ep7 The Chase

The Daleks are equipped with their own time machine, are on the trail of the Doctor with orders to exterminate him and the crew. They go planet-hopping in the TARDIS to escape them.It’s the Wacky Races in space! Sarah was so excited for a Dalek story and is very disappointed. Ian and Barbara assume the role of parents again as the Doctor and Vicki run riot through a dead planet (classic), a jungle planet (another classic), 1960s New York, a terrifying ship, and a ridiculous Hammer Horror haunted house. David tried to convince Sarah this grab bag of assorted nonsense is joyful and (sometimes) intentionally funny, but his even his boundless goodwill is stretched by the appearance of the mecho-Doctor.We’re sorry to see Barbara and Ian go, but let’s slide down this massive building and get the heck out of here!Firsts:  all the original line-up have changed, first on screen moment for new companion Steven Taylor,  first non-TARDIS time machine, and the first confirmation that the TARDIS is blue!
