I was less impressed with The Green-Eyed Monsters. A lot of the humour was based on the idea that men can't look after children. The plot didn't really make much sense, and the denouement was fairly bathetic.
The Dance Of The Dead, however, was a real return to form: a claustrophobic setting of the doomed space ship, the return of the Ice Warriors, and psychic possession - all worked really well for me.
The Mirror Effect, exploring the inner psychologies of Benny and the other regular characters from the series, could easily have descended into self-indulgence, but manages to avoid it through good writing and good acting. The ending perhaps a little over the top, but otherwise this one held together.
In summary: The Greatest Shop In The Galaxy and The Dance Of The Dead excellent, The Mirror Effect OK, and The Green-Eyed Monsters less impressive. Also of course The Plague Herds of Excelis is set in the middle of this sequence.
