We just watched S02, E01 of BBC's Trust Me. I'm not sure I've ever been more disappointed by a TV show.
The first series was brilliant. It was 4 episodes featuring a nurse who loses her job due to whistleblowing, and steals the identity of an doctor who's migrated, going on to impersonate her in her role as an A+E doctor. Good writing, good cast, decently written and shot. It's definitely worth a watch. Then Jodie Whittaker left to work on Dr Who.
Series 2 has a completely different premise, tone, cast, even cinematography. It's some ridiculous, poorly written 'murder mystery nonsense following a soldier who gets admitted to a hospital where patients are dying suspiciously. It literally have nothing to do with the first series other than the title, and being set in a hospital. Utterly shite. They should have just canned it after series 1.
