I like it, but it's almost a tinge too violent for me. I don't know why it bothers me more than say Sopranos or the Wire, but there's something about this show...
We mostly enjoyed SOA, but it quickly went from drama to melodrama, had some inane and pointless plot elements (some of which were just abandoned), some violence that didn't bother me on a emotional level so much as it did from a critical perspective because it was so gratuitous it was _silly_.
We recently rewatched The Sopranos, beginning to end, every episode over the course of about 2 months - it was just a good if not better the second time around.
