The first episode heavily features the overrated Essiedu putting on a low-rent Dr. Who Companion shtick. So it's easy to get fed up and dismiss the show. But you'd be missing some impressive performances from Anjli Mohindra, Rudi Dharmalingam and others, and Essiedu thankfully ends up just being a part of the ensemble. So it's well worth persisting to Ep3 at least, especially as the plot manages a degree of originality that's unusual these days.
