I see too much rubbish in TV, as my wife watches it! I try to read.
This should be a great drama, given the lead the writers and the slightly different concept. My problem wit most TV is that everything is so unlikely.
Trading offices wuld not have cleaners in during the work day - everythng on the screeens are too sensitive. Likewise, PCs and monitors would not be running when the traders are away from their desk, especially at night!
How many days did it take to look at the CCTV ?! (just saw that bit).
There is Artisitic Licence, and it is probably a neccessary element of TV dramas, but this is just ridiculous.
If you mssed it on normal TV - DO NOT pay a penny to see it.
