I just binged the first season in 2 days. What can I say, it's ok and I'll keep watching but it has some pretty big flaws in some departments.

There are some pretty big errors in the script and logic holes (phone number written on paper in 2022; drugs don't work like Dhalia, whoever thought the details in that storyline didn't snort a line in his life;[spoiler] everyone related to everyone like in soap operas; these Serbs are a joke when you think about how the Serbs were in the first Power.[/spoiler]

The acting is very hit and miss too. Joseph Sikora never seemed like a good actor to me, but he has a certain cool factor in the way he plays Tommy, so he was not the problem.
But JP and D-Mac, holy fucking shit I have no idea where did they find these people.. Vic Flynn will not win any acting award in his life either.
Tommy Flanagan and Lili Simmons are the only ones who really show that they are talented actors and love what they do. Show would've been dreadful without them.

I will keep watching but I really hope that it will become better in future seasons, closer to the quality of Power.
