There were always problems with Ozark's writing/plotting but for the most part, it got through seasons on good footing. While I liked this season overall the writing problems this season reached such a point that I just don't believe this show will ever reached the prestige TV peak it's aiming for.
These people waltz through the most dangerous possible situation imaginable like it's nothing. Safety is rarely an issue, they openly involve their children, they don't have security. Everything is sloppy. The way they discuss crimes over the phone. Openly allowing your son to work for a woman who you not only know is mentally unstable, but who is being targeted by the cartel. Followed by this season where they somehow semi bribe, semi convince the FBI to do its job on their terms. Everything works.
Javi could have been an interesting character. Criminal with a business degree...it was right there for the taking. I'm not mad that he was unhinged. But there's a difference between unhinged and returning to a potential crime investigation scene and killing a cop. And then returning again with Marty, to clean up the mess, and running into another cop who you almost kill until Marty stops you. Like what are we doing here at this point...that's just stupid television. I'm curious to see how he does as the king next season.
