I like the Sopranos a lot. It seems like a fully-realized and plausible depiction of a modern mob enterprise, and it contains a lot of really fine writing and acting. In some ways these sorts of serialized dramas have moved on a lot since it originally aired, though, and to me its overall quality is below that of, say, Breaking Bad or Mad Men. In later seasons, particularly the final season, there are just too many clunker episodes. Still, it broke a lot of ground and in general I think it's excellent.
