november 1983 mark the 20th anniversary of doctor who and i remember the medium coverage give to the event . scotland national newspaper have it centre page dedicate to the history of the show and britains best sell tv guide radio time have a front page cover and a multiple page feature on the show . there be even a special anniversary magazine from the radio time dedicate to the programme . but it be this one off special that really get the fan excite the plot centre around someone capture the different incarnation of the doctor and hold them hostage in the dark zone of gallifrey . okay it hardly a mind blowing premise and just set up the story whose main function be to reunite a many doctor and companion a possible and maybe the story be too cluttered with companion cameo for the story to work successfully and but at least we get to see some old villain like a dalek and a yeti and the cybermen take centre stage in this monster mash a entertainment for both fan and casual viewer it work very well and be one of the good story from the early 1980s . there be one or two bit that do not work like sarah fall down a mountain and susan twist her ankle but patrick troughton performance alone make this worth watching .
