Ok, I know that devoted fans will probably be horrified. Let me explain 
The good:
James Gandolfini. Fabulous portrayal of an extremely unlikeable, at times downright hideous, character
Edie Falco
Some very funny, sharp dialogue
Unflinching look at greed, self-interest, narcissism, unchecked patriarchy
Uncle Junior aka the most miserable git on the planet (but quite funny with it)
The Adriana-Christopher relationship - really upsetting at times but gripping and really well done. You cannot understand what she sees in him but she can't see a way out.
The bad (IMHO):
Lorraine Bracco. Dear god - wooden doesn't even describe it. She's always been utter rubbish. I wish they could have had an actor who was as good as JG so they could really spark off each other.
Every woman seems to be gagging to jump into bed with Tony. I know he's got a bit of an alpha male charisma going on but please, enough now.
The stupid Paulie subplots. Another wooden actor and I don't care about his mother or any of his other madcap escapades. Go away.
The number of episodes that seem to be filler. I'm halfway through season 5 and about 90% of it has been filler so far.
I am watching it as a box set so sometimes watch 2-3 episodes in an evening, but I am finding the relentless greed and ripping people off and threatening people and maiming people and general willy-waving a bit exhausting. I will stick with it to the end but TBH I do find it over-rated and I don't think it's something I will ever watch again.
Share your thoughts, got my hard hat on!
