TV Review: Classic Doctor Who: The Three Doctors (to mmvoe)

This is a 1972 opening series of the tenth season of Doctor Who, and is the first in which a prior Doctor comes back.  It features the first three Doctors, who are brought together by the Time Lords as the home world of the Time Lords is under attack, and their energy is being sapped into a black hole. Because of this attack, the Time Lords go against their own rules, and put the three Doctors together to attack the threat.  The Doctors are played by John Pertwee (third and current to movie Doctor) Patrick Troughton (second) and first William Hartnell (First).  The first Doctor is not able to materialize, due to insufficient energy, but appears on a view screen.  He is often the most level headed, and is sent to calm the other two down.  As the first two get together, they become engaged in a rivalry, which hinders their effectiveness.  The stream in the black whole is sent to find a Time Lord.  The Doctors eventually discern that they need to follow the stream, and so they do so.  There the find an old Time Lord Omega, who helped establish the Time Lord realm to begin with, but all thought he had sacrificed himself in an explosion.  His "will" has allowed him to exist where nothing should exist, in a black whole which is made of antimatter.  However as his "will" is what allows him to exist, he cannot leave.  He has brought the Time Lord to force them to use their will so he can leave.  However he has gone made, and actually the particles have destroyed his body, so he is an empty suit of armor.  Omega has accidentally brought many friends and others from Earth to the black whole, in his attempts to find a Time Lord.  He agrees to send them back, if the two Doctor Who's stay.  They agree.  However the use Omega's insanity and anger against him, and are realized, and restored to their natural spot, when Omega is set free through death.  The black hole becomes a star.
I found this entertaining.  The soldiers of the world created have interesting weapons, but they seem to always miss.   Their appearance is somewhat grotesque.  They energy being which is sending everyone to the black hole is a interesting special effect.
