I'm surprised they picked Spearhead. It's a bit slow in my opinion and there are better 4 part options available, including Terror of the Autons if they wanted the Autons. I think Terror does a better job with the Autons too and intros the Master. YMMV.
I think "Spearhead..." does neatly establish the Third Doctor's exile on Earth, the beginning of his association with UNIT, and his official working relationship with the Brigadier--all of them comprising a big chunk of the show's overall history. The Autons might just be gravy, but they could also serve as the link to the show's 2005 revival with "Rose," IMO.
