Currently re-watching it with one more episode to go. For some reason, I'd always considered it a weaker season. However, after watching again, I have to say it's a killer of a season - the New Jersey - New York tension; Christopher's issues; Ralph Ciffaretto; and of course the marital problems. For me, it's far superior to season 3 (Pine Barrens notwithstanding.) What a great show. I recommend giving it another spin (we've started from the first season.) God bless HBO for giving us The Sopranos and The Wire!
