Awful sloppy writing and production:
1. Do the murder suspects never get offered a lawyer?
2. When Bradford's wife is found and is "still breathing", the officer then goes on to do CPR
3. They move office building apparently but the interior stays exactly the same
4. That awful single note incidental music
5. The same blurry shots of the same officers in the corridors.
6. The murdering sergeant has a 2 digit collar number on his shoulder with no letters. Are there that few police sergeants in London?
7. A 4-person squad assigned to each murder - really, that's all that an MIT assigns? Mind you, they solve every case the same day.
I could go on......
.....if you add up the shots of the outside of the building, the same blurry people walking round the police station (2 ginger haired on the stairs, white shirted female brunette walking along the same place in the corridor etc), along with shots of buses, it can be as much as 14 minutes of each episode. It's actually more interesting to look out for these bits and tot them up than to watch the episode.
