I stopped watching after the blond girlfriend of Sopranos' nephew, Christopher, got killed by her fiancé, Christopher, because she had a friend who was FBI and she didn't know about it. I closed the TV at the scene where he is chopping her dead body up in the tub.
And I never really rewatched it since.
And I only watched isolated episodes, followed maybe 3 full seasons only...it got kinda repetitive and boring.
