I think its a great show. That said I can't dispute a lot of the criticisms over the past 4 pages of this thread. I guess they just bother me a lot less.
I wanted to re-watch S1/2 before watching S3 and had put it off, but I watched all 30 over the past month or so including about the last 15 in just two days. I thought S3 was the weakest of the three seasons but I still enjoyed it to the point where I could not help myself from starting the next episode.
For some specific criticism, I think they tried to do way too much in the 10 episodes they had to work with. Highlighting this was the last episode which felt ridiculously rushed. Like Marty got some stills to an FBI agent that resulted in US interdiction in Mexico against the rival cartel in a matter of hours? The worst written plot, to me, was by far the Darlene-Ruth-KC Mob triangle. Nonsensical. The show runners could have crowdsourced a more sensible plot from Reddit. I found that one GoT S8 levels of bad. Navarro's character didn't work for me at all. What was the point of rendering Marty and torturing him for a week? lol because he had spyware on his wife's phone? And how can you drop him back down a hole after he fixes your flagged offshore account in seconds? He's clearly worth keeping around just for that.
Finally, I don't get all the Ben hate. That actor is going to win every award a TV show supporting actor can win.
