I watched the first season right after watching Gomorrah as it scratched the itch of Italian Crime Mob and filled a void. Agree it was poor mans Gomorrah, but it kept me entertained nonetheless.
I just finished season 2. In retrospect I imagine if I re-watched season 1 again now I'd realize just how terrible it was. I almost quit watching season 2 several times but it was such a short season for some reason I decided to just see it out. It was so bad, it actually became entertaining when viewing through the lens of unintentional comedy. There are so many plot holes, so much bad acting, that I ended up finding it enjoyable for all the wrong reasons. In the finale there is a scene that's supposed to be shocking but I literally laughed out loud it was so bad.
In summary, DO NOT WATCH.
