The Red Road has been a fairly interesting 6 episodes. It hasn't always hit the mark and I feel there were plenty of opportunities to flesh out class and culture and race issues and clashes that weren't taken. The season is certainly guilty of racing through some themes and scenarios and thus a few of the episodes feel a bit claustrophobic. Had the season been 10 episodes it probably would have had enough room to breathe to be a great show. Instead, it is a good albeit rushed season.
It was pretty sweet seeing Gabriel Basso show up as Brian, Jean's long dead twin brother even though it was only for a moment (His younger sister Annalise plays the younger Jensen child). The Big C is one of my favorite Showtime series due in part to his acting. Julianne Nicholson's performance is its best and most fully realized in the season finale. Unlike the first half of the season in which she was pushed to the sidelines and felt a bit flat so it nice to see her more integrated into the main going's on.
I would very much like to see The Red Road get renewed and the ending of the episode certainly left an open door to a great plot thread. If, however, this is the last of the show, it was quite enjoyable while it lasted.
