Today I start a new review series, with an arc I've long avoided here. The Trial of a Time Lord (ToaTL) is, depending on who you ask, either a season-long, fourteen-part story or four, two- or four-part stories connected into a season arc. It comprises approximately half of the Sixth Doctors televised tenure in the role, and thus looms larger in my mental landscape than perhaps it should.
So because my reviews over the years have been particularly shy of Sixth Doctor adventures (at least the televised ones), I decided I'd finally tackle ToaTL for the first part of 2017 (with a Dalek breakaway—see what I did there?—for Power in February) before Series Ten begins.
As we begin this season, then, we see the TARDIS being pulled into a large structure in space, and the Doctor steps out—alone—into a darkened hallway. The room he enters is also darkened until, with some vaguely ominous words, someone eventually identified as "the Valeyard"—the person who is to become his major adversary over the coming episodes—reveals that they are in a Time Lord courtroom.
The Doctor is the subject of a hearing to determine whether or not he is truly guilty of "conduct unbecoming of a Time Lord." As part of his protest, the Doctor claims he can't be put on trial because he's Lord President of Gallifrey (Oh, Doctor... You sound unpleasantly like the new POTUS...), but is told that as a result of his neglect for his duties, he's been deposed.
