In Tooth and Claw, RTD finally gets to write a story with a reasonable plot at a reasonable pace. The opening scene, of the empty grassland, really made me think "Welcome to Royston Vasey - You'll Never Leave" - of course Mark Gatiss is part of the established Doctor Who Mafia these days. I would have lived without the "not amused" subplot, but maybe it's necessary to keep the younger audience with ADHD attuned to the programme. Pauline Collins turned in a splendid Queen Victoria, stern but not stuffy, though Crichton Wheeler must have done some of the editing, for the soundtrack over the rewarding of Rose just isn't a coherent sentence, it smacks of Splicer's Disease, perhaps it will be fixed in the DVD version. Unlike some, I though the Torchwood elements were neatly inserted into this story.
To be honest I didn't see a great story in School Reunion, but it was such fun anyway, it didn't matter. The moment when Sarah Jane sees the TARDIS is definitely the best of the series so far. Perhaps the equation-solving theme is a little reminiscent of the rarified Logopolis, but in a dumbed-down squeeze-it-into-45-minutes noughties way. Antony Head was an excellent villain; there seemed to be hints in Confidential that we may not have seen the last of him. (Speculates that the Face of Boe, Brother Lassa(?) and others will return for the season finale). I wasn't too fussed about the Sarah Jane - Rose thing; any fan of the old series knows who the winner will be there, but I suppose it will be interesting to find out how new fans reacted to this episode.
By writing in a boyfriend and a family, RTD has tied the series to Rose infinitely more than it ever was tied to the companion; no wonder the BBC want Billie Piper to stay. But that was never the way the series worked. It's a great strength to be able to replace your leading actor, but you lose that if you are tied by another role. It's not a particularly interesting plot line for me, but having had Mickey's comment about "the missus and the ex" during the episode, it was clever to twist that around at the end, by Rose's reaction to Mickey joining them in the TARDIS.
