Premise: The TARDIS arrives on Earth where T-Mat has revolutionised travel. However, the Ice Warriors have seized control and use T-Mat to distribute Martian seed pods across the world.
Notes: After their appearance in The Ice Warriors, the decision was made to bring the monsters back (partly due to the cost of the costumes not wanting to be wasted on only one story). The original story submitted by Brian Hayles was titled the Lords of the Red Planet which was to be set on mars but was considered unworkable. This story was then written instead but more problems arose when Frazer Hines postponed his departure and Terrance Dicks thought the original ending was lackluster and unworkable. He then re-wrote episodes three through six but Brian Hayles was the only on credited as the writer of the story.
Verdict: A brilliant serial with amazing characters and great performances from the whole cast. Mrs Kelly is one of the strongest female characters we've ever seen and Slaar is everything you'd want in a Doctor Who villain. However the ending (while written not to be so) still feels a bit lackluster while in a story that up to there has been very gripping 9/10
