The Glory Days When I think of the peak of the nu who era, I think of RTD last season, through to Moffat's second to last season - Season 4 to season 9.
David Tennant, Matt Smith & Capaldi were powerhouse actors in the role of the eccentric mad genius. John Barrowman, Billie Piper, Karen Gillan, Arthur Darvill, Alex Kingston & especially Michelle Gomez were absolute standouts as supporting cast.
The first season of Moffat's reign, and the last of RTD captured a certain kind of magic in particular. Now, some people may prefer Davies era, and there certainly were gems in there outside of the last season, but for me it was a bit campy. The show began to fall off IMO, when the BBC started to have priorities which were larger than capturing the essence of the long running show and Moffat grew tired of his role as showrunner. Both those things seem to coincide.
Chibnall's era started with a casting choice (Whittaker) that I don't think reflected the identity of the doctor at all. You can complain that she didn't get good writing, but I don't think she ever had the correct range for the character. With so many audiobook, book and guest writers on the show, many of whom are deep fans like Moffat was, the choice not to let any of them run the show seems quite conscious. Like they were producing something they wanted the fans to like, rather than producing what they actually liked.
Now, looking back at the end of this era of nu who given the show has been rebranded I can honestly say there are amazing gems in here, in this long running regeneration of the beloved franchise.
Silence in the Library. Forest of the Dead. The Time of Angels. The Big Bang. The Pandorica Opens. The Impossible Astronaut. The Doctor's Wife. Heaven Sent.
These are gems that will live forever in Who lore and fandom, no matter what happens to the show or the BBC, and I don't think that a two-three season drop off at the end of this Nu who era should brandish what was over all, an incredible run. It was a hell of a ride.
