TV Review: Doctor Who: ***^The Pyramids of Mars

This is from the Tom Baker (1975) era as The Doctor with Sarah Jane (Elizabeth Sladen) as his companion.  It is available through instant Netflix.  I remember this show from when I use to stay up late and watch it on PBS in Utah--television style.  You had to stay up late sometimes to catch all the episodes in a series.  This has four episodes.  The Doctor lands on Earth in the past because of a temporal shift.  This shift is caused by an ancient monster/god of some power named Sutekh who was imprisoned by the other gods of the time on Mars.  There is somehow a connection between Sutekh and and Egyptian pyramid.  He inhabits an archaeologist, at least mentally, when he discovers the ancient tomb in Egypt.  This puts in motion a series of events in which Sutekh plans to fee himself by firing from Earth a rock at Mars to destroy the mechanism which is keeping him captive.  The doctor has to thwart this plan as Sutekh hopes to enslave everyone and take over the universe.  He apparently has power to do so if he were free.  The Doctor is able to destroy the rocket, but only by confronted Sutekh directly, who takes him prisoner and discovers he has a TARDIS which will easily help him in escape.  However the Doctor thwarts him with the control mechanism to the TARDIS which he attaches to the temporal shift machine Sutekh is using to travel to Earth to take control of the TARDIS.  An intriguing story.  Sutekh has some mean robot mummies, and the original archaeologist makes a good monster, looking like Boris Karloff.
