I never watched it while it was on, but I happened to catch the last half hour of the finale because it ran into the late news....and I was intrigued. So, I've been watching episodes from the beginning on u-tube. (No commercials!)
I find it very well written and the acting is impressive, although there seems to be a lot of crying by the guys.
With as many plots, sub-plots, flashbacks and interwoven story lines, the writers and producers did an amazing job in keeping the theme and character developments so coherent.
I'm really enjoying it, espcially since I'm home, not feeling well, this Memorial weekend.
Maybe I can come back here with any questions I might have as I keep watching.
(Or maybe someone can give a couple links where the series plots were discussed?)
