When the Sopranos ended its television run, it did so in such a fashion that it had its fandom up-in-arms, cursing and wondering what the hell happened to their favorite show. It ended with a hard cut to black. No one knew what would have happened next even though the episode built up to a climatic ending. Boom, without warning, the series ended.
With this type of controversial ending now possible, LOST fans worried that its show runners would also try to pull a large "fake out" to avoid answering the calls of diehard fans for answers to the key mysteries.
The writers did try to get out of years of story layers when they thrust upon us the flashforward universe, where the characters were living different lives but apparently in the same island time frame. It began to call into question whether the flashbacks were actually truthful portrayals of the characters prior to the crash landing on the island. For if the flashforwards were not "real" in the sense that that universe was merely a holding world until the souls of the friends could reunite in the after life, then the same could have been true of the flashbacks (which contained some serious medical and legal errors). If the flashbacks were a dream state, what was the island? A collective dream state or purgatory as speculated by some season one viewers.
LOST viewers never got the clarity from the producers about the last season. We were merely told that the show was always "character focused" so they did not have to answer the complaints.
After many years of debate, Soprano fans got their answer. From recent NY Post article:
The Sopranos” creator David Chase accidentally spoiled the finale during a leaked interview for his book celebrating the Emmy-winning HBO mob drama.
At the end of 2007’s final episode, titled “Made in America,” Tony
Soprano (played by the late James Gandolfini) is eating out with his
family amid a turf war between the New Jersey and New York Mafia
families while an enemy hit man waits in their midst.
The screen then fades to black as Journey’s “Don’t Stop Believin’ ”
blares on the soundtrack, leaving it ambiguous whether the show’s star
gets whacked — until now.
Spoiler alert: In the roundtable discussion, co-author Alan Sepinwall
asked Chase, “When you said there was an end point, you don’t mean Tony
at Holsten’s [the diner], you just meant, ‘I think I have two more
years’ worth of stories left in me.’ ”
Then Chase, 74, dropped the bombshell: “Yes, I think I had that death
scene around two years before the end … But we didn’t do that.”
Noticing his epic leak, co-author Matt Zoller Seitz chimed in: “You
realize, of course, that you just referred to that as a death scene.”
“F - - k you guys,” replied Chase upon realizing his blunder.
