Includes possibly the best cliffhanger of any Doctor Who related property (including the main show). Part 1 has so much drama packed into a 28 minute kids show: Maria’s dad wants to take her away; Luke’s “real” parents exist and desperately want him back; Sarah-Jane investigates seemingly unrelated telekinetic powers; Luke’s parents are aliens and his new brother is a telekinesis genius; shock - the new family is revealed as Slitheen!; bigger shock - Mr Smith is villainous and has been pulling the strings the whole time and kidnaps Clyde! WHAT?! And that’s just part 1. Despite all the various threads the show flows nicely from plot point to plot point. It’s exceptional writing. Oh. -and K-9 turns up at the end!!
