I purchased this documentary when it first came out and it was really one of mixed emotions. Overall it was very well done and the production quality was superb. I just watched it again last night and I was still left wondering what story and/or what presentation of pipe smoking was the producer trying to tell? There were so many storylines interwoven into one documentary, and as vosBghos above says, an overall air of melancholy which casts a pall over the entire hour. I mean, in such a short time-constrained documentary, what value of is it to show the sadness of Lee Erck - nearly in tears - over not having children of his own? Then there was the death of Mimmo's father, which was also quite sad. The portion with Lars Ivarsson, who at the time of filming was most certainly battling terminal cancer, reflecting on his life and speaking in a very general manner on his pipe making, left me wanting so much more.
I'm glad Father of the Flame came out - I think it's valuable work, but my opinion is that it missed the bullseye of presenting the joy of pipe smoking, its rich history the world-over, its presence in previous generations, and why it still (even more so) relevant in this present time. This isn't some hobby or passion of bygone generations, and I fear that is what many non-pipe smokings viewers could infer.
Just my 2 cents
