The writing quality for the last two seasons went down significantly, but this episode hit the absolute lowest.
This show was never realistic, but it managed to feel very natural, the acting made it very believable. But the way all the characters act now is very cringe.
The spitting scene, the women fighting, the bull scene, the execution scene, the sniffer dogs, and Rene's over-exaggerated expressions. All of these are just the worst combination of bad acting and bad writing.
Thankfully the overall story makes enough sense that it is possible to finish watching the series. And it is one of my favorite shows of all time, but watching the last two seasons is really painful at times.
