Been watching all four series over the last couple of weeks. All still available on I-Player at the moment. A few observations/predictions :-
First time I'd seen series 1 and I reckon it was probably the best of the lot.
I agree with a lot of folk that the formal interview scenes are the highlights.
Best single episode - the first one of series 3 when Daniel Mays was outstanding
Worst bit - the ending to seies 3 from the moment Dot Cotton's accomplice , an armed cop, started shooting in the AC-12 HQ to help Dot escape. A "jump-the-shark" moment for me . Reminded me on "Between the Lines" which was a similar BBC drama from about 25 years ago. The first two series of it were brilliant , and well worth tracking down on You Tube. But after that it went more action-and-adventure , than police internal complaints procedures.
Hastings can't be bent , can he ?........but I think his Masonic links could be played on a lot more in the next series
Dot Cotton's dying declaration about "H" is a red herring. He was clearly a very bad apple , so it's obvious that he was actually trying to say "H-E-A-R-T-S......if you cannae spell it....."
The closing scenes in series 4 didn't mention Jamie being disciplined or sent down or anything like that. Or even that he changed his name to Max Lowe and joined the Witness Proection Programme in Aberdeen on loan from Derby. Anyway , I wouldn't be surprised if he features again somewhere down the line.
Hastings will get into Kate Fleming's knickers before too long as she's got the hots for him. That's what the furtive looks between them at the end of series 4 were about.
I'd love to se the wee scrote who was Tommy Hunter's gopher in series 1 get his comeuppance. The one who was going to cut off Arnott's fingers with the bolt-cutters.
Order of widness -
1 Arnott's girlfriend - the cop
2 Georgia who got flung out the hospital window
3 Jill Biggalow / Polly Walker
4 Jackie Laverty / Gina McKee
5 Kate/ Vicki McClure
6 Denton/Keeley Hawes ......Only because we know from other programmes that she scrubs up a lot better than Denton
