I do really like how often I'm seeing people defend Frank's character by saying it's supposed to come off as terrible acting. I thought such comments would just be reserved for dumb soccer Mom's on Facebook, but it's starting to sneak into arguments here. Like Vince isn't a bad actor, but such a good actor he's portraying the character as badly acted because the character is supposed to come across as a laughable, bumbling fool nobody, including the viewer, takes seriously.
I'm gonna go ahead and say that since other characters have also gotten some really bad lines they looked physically pained and confused they were being forced to deliver that it's faulty logic to say Vaughn's character is supposed to be that way. Maybe that's what Nic tried to do, and a combination of bad writing and bad acting failed to convey the 'putting on airs' notion, but in the end it's just poorly written dialog for a poorly conceived character, and without a strong-voiced director to lipstick the pig.
Have read several articles talking about on-the-spot polishing of dialog, particularly Woody adding humorous lines to call out Rust on his bullshit. Would Season 1 have been different if we didn't get Marty saying shit like "let's make the car a place of silent reflection" and echoing our skepticism, while still allowing Rust's philosophy to exist in a way that created theme and mood and allowed introspection. What if we instead got the model we see this season where everyone looks confused after a ham-fisted would-be-philosophical line is delivered and the other actors look confused or almost like they're about to bust up laughing.
Would still probably be bad this season, since there is only 4 months going into it instead of 4 years (and Nic didn't have anyone to 'sample' philosophy from this year so it seems all his own), but again I think Season 1 was helped a lot by professionals in the industry with the know-how and balls to speak up, and maybe this year Nic felt he was badass enough he didn't need such help or is just not getting it. Because there's no way in hell a bunch of these worst lines make it through unchanged by edits, rewrites, directors, or actors unless the original writer and show creator is there refusing to allow any changes. One of the reasons I find this show such a trainwreck is after a lot of credit going around for Season 1, Nic made sure he got the bulk in Season 2, and it's not looking like that was a smart decision.
