Good one.
On top of what I've already said, The Sopranos' ending is one of the most discussed and widely known TV endings of all time. If you don't know that it "cuts to black in mid-sentence" then, frankly, where have you been? Loads of other popular TV shows have referenced it, like Family Guy and Bojack Horseman; it's been parodied and remixed all over the place by loads of different people. And just from my own experience, I took my fiancée through The Sopranos for the first time this year and even she knew about the ending despite not having that much of an interest in big drama series. It didn't affect her experience, it's just one of those things people know about.
Instead of just calling me a "sad ****", please tell me where we should draw the line with this stuff. Because I think 16 years is far back enough to safely discuss it in the open. Should we never discuss the Dallas shower scene again without spoilering it, or never mention "Who shot JR"? Should we never make reference to "We were on a break!" because it spoils the major plotline of the first three seasons of Friends? Should nobody mention the Red Wedding in this thread because it might ruin the entire experience of Game of Thrones? Are we banned from discussing Who Shot Mr. Burns? Children have been born, raised, and finished school since The Sopranos finished. I think it's fair enough to discuss it out in the open and I've put my argument forward.
Why don't you do the same instead of just calling me a "sad ****"?
