This week’s episode of Doctor Who saw the Doctor (Peter Capaldi) and companion Bill (Pearl Mackie) head back in time to 1814’s great frost fair on the frozen river Thames, and viewers were loving the period setting.

Especially if it means getting Peter Capaldi into the most appropriate of headgear…

The Doctor and Bill discovered that under the ice there was a chained-up sea creature, who was feeding on unlucky fairgoers – including one young pickpocket, much to the surprise of viewers.

Can we just appreciate that #DoctorWho had the guts to kill off a kid and not bring him back!!!

Whoever thought we’d be applauding Doctor Who for killing off a child before 8pm? What strange people we are.

Anyway, the whole thing was building up to two hugely satisfying moments, which set the internet alight. Moment 1 – the Doctor punching out the lights of baddie Lord Sutcliffe (Nicholas Burns), who was feeding people to the creature AND had a sideline in racism.

"Thin Ice" contains the most satisfying punch thrown in the history of #DoctorWho.

And then came moment two – the Doctor making a powerful speech about the value of human life, which seemed particularly relevant in troubled political times.

I could live 2,000 years and not get over that speech! #DoctorWho

In the end the Doctor and Bill saved the day, some lovable street urchins were rehomed and everything worked out just fine (except for Lord Sutcliffe) – and fans were happy to see the series continue in its purple patch of great episodes.
