Delta and the Bannermen has such a different and strange tone for the show - light, frivolous and fast - focusing little on details. I initially found it tricky to get into because of the huge cast of characters but once I locked into the relatively simple story I fell in love with the settings, characters and weird change of pace in part one. The Doctor at a Welsh holiday camp filled with shape shifting space visitors in 1959 must be the most Doctor Who-ish concept ever.

Part two and three are much looser limbed and aimless. As with much of this show nowadays a promising premise gets lost in a lot of running around. This is compounded by the sheer number of characters clouding what should be a pretty straightforward story. The two American comic relief characters for example should have been cut - this would have allowed time for the plot to be explained in a less perfunctory way.

The Bannermen never really posed any kind of threat, just chase scenes. I was a fan of the Welsh girl though. Sylvester’s Doctor continues to impress - how he smashes what he’s given is mad. Imagine how good season 22 would have been - better scripts and a much more powerful lead actor. We can dream.
