The Sopranos ending

Chase is on record as saying that

Tony did not get whacked

From the same piece:

"There are no esoteric clues in there. No 'Da Vinci Code,"' Chase
states matter-of-factly.

And he feels the show concluded on a hopeful note.

A.J. will "probably be a low-level movie producer. But he's not going
to be a killer like his father, is he? Meadow may not become a
pediatrician or even a lawyer ... but she'll learn to operate in the
world in ways that Carmela never did.

"It's not ideal. It's not what the parents dreamed of. But it's better
than it was," Chase says.

As for the blackout midway through Journey's "Don't Stop Believin',"
Chase had wanted the show's ending to be even more abrupt.

"Originally, I didn't want any credits at all," says Chase. "I just
wanted the black screen to go the length of the credits - all the way
to the HBO 'whoosh' sound. But the Directors Guild wouldn't give us a
waiver."

The choice was an artistic one, and was not meant as a slap in the
face to fans.
