My favourite of the second season plays: we have the return of Lucie's aunt Pat, but also Stephen Pacey (Tarrant from Blake's Seven) as her husband Trevor, the eponymous Zygon Who Fell To Earth, and Tim Brooke-Taylor of the Goodies as the Zygon second-in-command. It's a really fun tale of nostalgia both for and in the 1980s; I loved every minute of it. ( )
