This is the seventh season of "Once Upon A Time" at ABC network television,
and the announcement is now official:
the seventh season is the last season.

As far as network broadcasting goes,
"Once Upon A Time" is now at mid-season.
There were a bunch of shows in autumn,
with a mid-season finale in December.
The big reveal concerned a coven of witches.
For Lana Parilla's Regina, and for her son Henry,
there were some very personal concerns there.

But Rumplestiltskin and Captain Hook
-- in their City of Seattle personae as plainclothes detectives --
had a limited amount of things to connect them
to the witches and their carryings-on.

So the remainder of Season Seven is now being shot/filmed,
with a number of the episodes all ready for broadcast
and a few more still getting prepared.

With today's announcement that this season is the final season,
and the season finale will be the end of the show
(broadcast date in early May 2018),
all the press releases and interviews
center around the two showrunners who often write episodes
and who supervise a bunch of additional writers.

I have yet to see interviews with the actors.
