The last episode completely ruins the whole series for me & the fact that Nadine was kidnapped and no one even checked places she could have been and was murdered and fish didn’t even bother to try investigate it even though he knew what had happened and who done it baffles me.
Overall the acting is pretty good especially by fish in the show and it also highlights a bad justice system and how overly protected cops are in it but the creators of the show as mentioned in the first paragraph seemed to have wrote in that fish knows that Nadine was murdered and who did it but doesn’t even bother to investigate it, in which would have had a witness to her kidnapping outside the dog centre and most likely CCTV footage of it happening and should have dna from Osorio under her fingernails from the scratches she left.
