The Diary of River Song: A Requiem for the Doctor by Jacqueline Rayner (Big Finish, 2018) A somewhat predictable story overlaid onto its historical setting (rather than using it to any intrinsic purpose). Alex Kingston and Peter Davison work well together but cannot mitigate the feeling of treading water. The Doctor’s new companion is presented without any explication.
River Song: Five Twenty-Nine by John Dorney (Big Finish, 2016) One of the better Big Finish stories, not offering full closure but nonetheless presenting a global extinction event with sombre melancholy. Sans any of the Doctors, River Song is given space to make the programme her own. Alex Kingston does just that.
Doctor Who, Doom Coalition 2: The Sonomancer by Matt Fitton (Big Finish, 2016) Fitton manages some strong characterisation — Liv Chenka takes charge; Helen Sinclair bonds with River Song — but although Alex Kingston is quite the drawcard, the lack of interaction between her and Paul McGann is disappointing, as is the plot degeneration into runaround dénouement.
Doctor Who: The Husbands of River Song by Steven Moffat; dir. Douglas Mackinnon (BBC, 2015) The 2015 Christmas Special takes a lighter approach than its predecessor, and not since Blackadder II has a severed head been played for such laughs. Peter Capaldi captures something of each of the first four Doctors while Alex Kingston nails her swansong.
