It was very satisfying to re-acquaint ourselves with these engaging characters. The series, as ever, was well-constructed with judicious and effective use of flashbacks. Final twist ending/conclusion was satisfying if not the sentimental ending one would like. This series in particular reminded us that the most important theme that underpinned the whole series was friendship and this was constantly dealt with in a thoughtful and non-sentimental way.
However, the whole series did (necessarily?) soften and sweeten the actual real-life effects of such trading/business. Not to be forgotten.
