There's been plenty of bland, pish Doctor Who, both new and old, before now. So I can't see it as suddenly being reduced to this level.
There's been plenty of poor Doctor Who in the past, but there was at least a sense that they were trying to do something good. The reduction in quality has been sudden. Compare this years series finale to last years finale and the gulf in quality is enormous. While there have been huge dips in quality between stories before - for example, Caves of Androzani being followed by The Twin Dilemma - they still existed in series where something new and exciting was just around the corner. Unfortunately, with Chris Chibnall in charge of the show, there is no sense that anything even passably good is just around the corner. 'It Takes You Away' feels like it was a success in-spite of its producer, rather than because of him. Ultimately, the problem with the show now is Chris Chibnall, and that's why there's genuine concern about the show so long as he's in charge.
Yes, Season 24 was pretty poor (aside from Paradise Towers), but in both Delta and the Bannerman and Dragonfire I could at least see that they were trying to do something worthawhile. Bear in mind that Season 24 was a season rushed to production so that the new script editor, Andrew Cartmel, didn't have enough time to turn the show around so that it reflected his future vision for the programme. He was, however, able to sow a few seeds which would later blossom into the, ultimately curtailed, Cartmel masterplan. So while Season 24 was pretty bad, there was light at the end of that tunnel, a sense that the show was in a transitionary phase. As of now, there is no light at end of the tunnel. We have Chibnall and his surface level scripts and basic ideas.
I'm quite sure I'm not alone in not wanting to bash either the show or production team to this degree. But, ultimately, it's because I care, and it matters to me that Doctor Who should be quite this vapid.
