I agree, Bethberry, I wouldn't apply Hugs N Learning to the Scouring. The hobbits encounter an unexpectedly unpleasant situation which, thanks to their experiences, they are able to deal with effectively.
There are no hugs - except perhaps off-stage between Rosie and Sam
- and they have already done their learning. As for Frodo, he is not reconciled at all and ends up leaving for the West.
The most annoying Hugs N Learning scenes take place outside, in a rainstorm, with both protagonists weeping and drenched, and finally falling into a sodden hug.
I have seen this very scene played out in a dozen or more films, nobody ever has a row during breakfast or in the car, it all has to be conducted while being battered by the elements.
Oh, and I understand that the current film version of Pride and Prejudice contains an extra six minutes of solid Hugs N Learning for American audiences only.
