Season one was all about Rust and Marty obviously, but the third main character was the setting of the rural god forsaken parts of Louisiana that they were in. I mean this is exactly what I feel and love in like SuperGiant games. One of the towns I grew up in till like age 7 was a sub-10k population dead end town, and I could feel little glimmers of that, along with it's own unique Louisiana taste, culture, and occult.
In contrast, Season 2 seems like it's going all over generic California, we never stay in one place, and even though we're told about Vinci as a deadbeat town and Frank trying to raise up new shit following the rail line, all we're actually shown is basically more generic California without any real taste, clubs and street shots without anything interesting filling the world, and I don't even know if we've ever even been directly in Vinci besides the PD because everything looks like the same ass California, and that's a problem.
Meanwhile, it can be argued that that's not the focus, and that's fair, now they have 4 main characters to focus on, Frank whom in my opinion has still flatly acted all his way up to "I want to go back to being a thug for my money" plot, Knifelord whom so far has an I hate my family but look at my sex and knife shit subplot, Colin's kid-not-kid and struggling with pretty much everything in life, and I don't know his name's struggling with his struggling to be not be homosexual subplot.
Honestly, on a base level most of the themes in the story are already generic, all I'm enjoying so far is the Colin mustache's sideplot and pretty much every scene he's in. Likewise, I'm enjoying Knifelord's portrayal even though so far her actual sideplot is whatever, everything else I really could not give a shit about and every sprinkle they give is barely one full percentage of something given from it's predecessor (ala Sopranos or whatever). I'm still watching and enjoying especially for Farrel's stuff, but this is the half way point and so far there's very little about this season if anything at all to remember it 10 years from now, and while season 1 was slow to start, it piqued my interest as something unique very quick.
