Two driving forces really stuck out to me. First, the old cop taking those tapes and giving them to Danny. That seemed completely unrealistic to me. It's not like he couldn't and didn't figure out what happened up to that point. And did they not interview Danny at the time? Furthermore, his oldest sibling at the time was 14, so of course he's going to do what he did, along with his younger siblings. I guess the implication is he thought that John was the one who came up with the hit and run story and therefore hates him for it, but even that is pretty weak. Also, wouldn't the dad's will have the mother be the beneficiary of everything rather than the kids? If Sissy Spacek was also dead, it would go to the kids.
Not sure how season 2 is going to play out with the son. He will be a constant reminder of Danny. Also, I'm pretty sure the hispanic/ex-alcoholic guy was eyeballing them at Danny's Miami place, so there's a problem there. And again with the old cop, who has somehow figured it all out.
I think my main problem with the show, however, is that it really offers nobody to root for. Almost every character is a POS. John is the most likeable, but he's pulled down by all the other POS people in his family. It's like that movie about the dysfunctional family with Meryl Streep and Julia Roberts where they spend the entire time yelling at each other. Just a lot of people needing killin' in this show.
