With Fugitive of the Judoon Doctor WHO becomes unexpectedly Doctor WOW, with Whittaker's best episode yet and one of the best episodes in the series ever.
It has a very different feel to what we've seen before. It may be because of focusing on a very different character than usual, Ruth, or it taking place in Gloucester (rather than Sheffield), but whatever the reason the results make for an absolute top episode in which the twists just keep coming.
Also by bringing back both a known alien race and a very beloved character we haven't seen for a long time, it ties Whittaker more to her earlier incarnations. Because of the look of the new show, and maybe because of having a female rather than male, her series so far felt like it stood a little on its own. Now it feels much more connected as a whole.
I hope this episode brings back a lot of viewers who left, because it certainly deserves it. If it can keep this up, the rest of the season should be a blast.
