Excelis Decays is rather looked down on by fandom, but I think it is one of Sylvester McCoy's best performances, matched once again by Anthony Stewart Head and also Ian Collier, Mark Gatiss and Penelope MacDonald (sadly not so much by Yee Jee Tso). The Excelis sequence has done well on portraying settings, and the totalitarian militarised society is utterly convincing, as is the Doctor's outrage at the situation and his bleak acceptance of the generally tragic ending to the story, and the wrap-up to the overall plot arc. Somehow it really grabbed me; I find McCoy as beak!Doctor compelling. ( )
