Brilliant, joyful, heartrending by turns. And a great ending, entirely unlike where we thought we were going. And they filmed the last scene with the two teens YEARS AGO to have it ready...so they knew where they were going, something that VERY few series today actually plan.
I wonder if they filmed only that ending or if they recorded multiple endings (like the SNL skit with Tom Brokaw pre-taping ever possible news story before he went on vacation: "Tragedy today, as former President Gerald Ford was eaten by wolves. He was delicious.")
And they couldn't have telegraphed what would happen to the mother more if they had Samuel Morse handle it.
