I enjoyed this and binged it over two evenings. Most of the cast, except Brian Bovell, are unknown to me. But all seem to me to be convincing.
Bit puzzled by the reviewer who asked ' where's the men'. Did this person watch a different programme? Let me see. The A&E consultant: a man. One out of the two investigators: male. One out of the two juniors: male (and not a nurse as erroneously mentioned. Strong hints that it's a 'women good, men bad' show. Apart form the husband who's not written as bad. The junior doctor, Oscar, not written as bad. The investigator Dr Adjei, again not written as bad. The barrister Sir Anthony Owusu, again, not an evil character at all. On the other hand, the 'strong female lead' character could be considered morally dubious at the very least. So matey your argument doesn't stand up. But I guess those who feel their tv shows should mainly feature straight white men of noble character then you might feel a bit miffed. Still I say the husband's a good'un.
One or two things I'd query. Bit surprised the police weren't involved a lot earlier on. And yes, how did the MIU people get hold of phone record?
Apart from that worth a watch if you like thrillers involving a big conspiracy going right to the top.
