From The TV IV

Season Twenty-Six of Doctor Who premiered on September 6, 1989.

What some regard as a bit of a return to form for the series, the final season of the original series features four stories, three of which are fairly highly regarded (The Curse of Fenric, Ghostlight, and Survival) and one which is considered below par (Battlefield, which suffers from a truly terrible score). This season sees the return of two popular characters, the Brigadier and The Master. Interestingly enough, and probably to cover for the completely lack of any budget, the final season is completely Earthbound (excepting a few parts in Survival).

This season has a recurring theme of evolution, with social darwinism being large themes in Ghostlight and Survival, and a possible branch of humanities' evolution shown in The Curse of Fenric. Another emphasis of the season is on Ace's backstory, culminating with her returning home to meet her friends in Survival.
