4/5

As a couple of men who resent their Slough House assignment but are driving to it, feeling a reluctant esprit de corps anyway, River and Lamb are now on the same page.

B+

I don’t want to give the impression that “Circle Of Life” is strictly a slog, because the show itself is still clearly having some fun, even if none of its characters are. But we’re still clearly in for a Bummer Season...

8/10

Now under new management, Slow Horses Season 6 kicks off as tonally consistent as ever, even if it occasionally comes off as a little too try-hard at showing just how well it understands the Apple TV show’s moves.
