The first three series of Gallifrey audio plays make up an excellent, fast paced adventure series that has something of a John Le Carre feel; a political tale but told within a science fiction setting. The performances are strong, the plots complex and the series builds to a cliff hanger ending. As someone who had enjoyed these plays, I was delighted to find another series had been released; my delight ended as soon as I started to listen. The complex threads of the previous cliff hanger ending are brushed aside within a few lines, as the characters drift through a tedious series of 'alternative' versions of Gallifrey via a portal that pops up now and then. These 'other' Gallifreys include some deeply silly ideas, from Romana being married to Andred, to a female Borusa. Each story visits another Gallifrey that isn't Gallifrey, and it is hard to care what happens on each, as they are not the real Gallifrey. The energy and excitement of the previous CDs is completely missing, as is the theme music, replaced by a vastly inferior one, and it really is hard going to sit through all four dull stories. After the previous series this set is a staggering letdown from start to finish. There are many excellent Doctor Who CD plays available via Amazon, many of them from Big Finish, sadly Gallifrey Four is not one of them.
