Doctor Who: Every Thirteenth Doctor Episode Ranked From Worst To Best

Praxeus is an episode that gets much, much more hate than it deserves, often lumped in with the deplorable Orphan 55 on the basis that both preach an environmental message. Praxeus, however, does this in a much more organic way by tying it into the plot, and it also doesn’t patronise the viewer.

In addition, having the Doctor fight a disease makes for a welcome change to the monster of the week format, with the practical and visual effects involved resulting in some genuinely creepy and brutal deaths.

We quite liked it, honestly.
