Spearhead From Space marks the start of a brand new era for the Doctor Who mythos, for the slate is pretty much wiped clean as is evident from the ending of 'War Games'. This was the first adventure to be shot in color, to be shot entirely on film, and features the newly regenerated Doctor, exiled to Earth, and now reluctantly has to rely on the resources and support of his old friend Brigadier Lethbridge-Stewart, and U.N.I.T. to give him shelter, while he continues to lend his remarkable intellect to defending the Earth against alien creatures. This remains a marvelous adventure as it also introduces the Nestene, the Autons, and a brand new companion in the form of independant, intelligent, Cambridge scientist, Elizabeth Shaw, the proverbial Scully to the Doctor's Mulder. This adventure, along with all of Jon Pertwee's adventures as the Doctor stand the tests of time, as it never feels in any way dated or time frame specific, considering it is the 1970's, but you never feel as if it is the 1970's in anyway. The Autons are highly effective creatures, serving both as foot soldiers, and as physical hosts for some of the Nestene energy within the pods that landed on Earth. Definitely highly recommended for Dr. Who fans.
