For one, the pacing is terrible. They spent huge amounts of time on plot points that we either don't care about, or we know are going to lead absolutely nowhere.

The ending of part 1 had Ruth out for revenge on Javi, which is then totally done with by the end of the first episode of part 2 (because it's obviously super easy to kill a cartel boss), but not before we're treated to an entire episode of listening to Nas on repeat. So now all that's left for Ruth is to plan a hostile takeover of the casino (lol) with a character I'm pretty sure everybody had totally forgotten even existed.

Also, we have the grandfather in town looking to take the kids away from Wendy, but we know that can't actually happen if you remember the car accident they showed in the first scene of part 1. What was the point of that btw? The only purpose that served was to take away any tension of something happening to the Byrdes until that crash, which was halfway through the final episode. And then it ended up being a complete nothingburger. Wtf??? Oh, and how about Wendy being willing to kill literally anybody, including her father, to "protect" her family, but she draws the line at voter fraud. Just lol.

The final scene was too stupid to even put into words. A better ending would have been to have lumberjack Dexter jump out from behind the bushes and kill the Byrdes with his chainsaw. Seriously.

I have a bunch more things I could nitpick, but this is too long already. Basically, I thought it was just really lazy writing, and pretty dull overall.
