Once he’d done that, admittedly, there was quite a lot of it: a lot of shooting, plus things blowing up.
But while such scenes are obviously par for the course in a good many TV dramas – and perform an eye-catching job on the trailers, of course – here they’d been held back until they actually meant something, until we knew enough to care about the people in danger.
There was violence and gore in abundance, but such was our emotional investment by this point that it wasn’t remotely gratuitous.
For example, we’d stopped finding Keeley Hawes’ character, Home Secretary Julia Montague, wholly unlikeable.
It seems she’s more than just the snooty madam she’d appeared to be in episode one. That said, I’d still think twice before inviting her to dinner.
As for police officer David Budd (Richard Madden), the ex-Army chap assigned to protect her from those who wished her harm – and we did get the impression there were quite a lot of those – he’d shown us as much of his private, mentally frail self as he had his buttoned-up, robotically efficient on-duty persona.
Most intriguingly, episode two took the personal relationship between this pair to a significant new level.
That’s probably the bit we could most easily have predicted, but where it goes from here, as Budd wrestles with his conflicting loyalties, is anyone’s guess.
