Continuity

Every depiction of the drug money bring counted or transferred in large quantities (ie in bags) shows absolutely pristine notes, whereas the occasional shots of money being exchanged for drugs show crumpled, folded notes.
Factual errors
In the opening credits letters in the names are highlighted in green so as to represent a chemical element symbol. However, Michael Slovis, the Director of Photography, for several of the beginning episodes, they highlight the Ch. There is no chemical element symbol Ch. After a number of episodes they caught it and thereafter they only highlighted the C.
In the opening credits, both "Br" (Bromine) and "Ba" (Barium) show 2-8-18-7, which is the Electron Shell Configuration of the element "Br". However, the element "Ba" should have shown an Electron Shell Configuration of 2-8-18-18-8-2.
Revealing mistakes
