I completely agree. I always found Farrel kinda iffy, but came to like him for the In Bruges film. He pulled of that tough role very well. Vince Vaughn's career was dead, last known for being a bit overweight in failed rom-coms. Boy, what he did was intense. Great acting by these two.
I found this analysis very good:
I think many people dont like it because ist to ambitious in what it and how it is trying to tell the story. Contrary to ist essense many scenes come across tacky if you dont get what these layers are. I think if people try to watch 2-3 times they would at least immensly respect the many deep layers going all over the place. I can understand people not liking it, expecting the usual thing on TV and not delving in to it, but I for one love movies like this series over pretty any much genre. A quality series is always better at fleshing out a story compared to a 90 minutes movie.
Hats off for all involved. Hope the series gets the respect it deserves when ist on DVD and more people get it.
