Just seen it. Underwhelmed is probably the best adjective I feel.
An awful lot of soft-focus filler. The whole story could have been told in 30 minutes. With adverts.
And "Guitarisan" ? Pur-lease. It's Luthier. We don't need a new word. One can only speculate how much they had to pay the poor guy for his dignity.
Guitars almost always have serial numbers (Hofner would have). So all of the verbiage about looking at photos, pretending you are some sort of CIA analyst - again pure TV fiction. There is no way someone who moved in the circles McCartney did when the bass "went missing" (yes, the length of the piece was an attempt to obfuscate the story) would not have recorded the serial number. And if they didn't, his management needed sacking.
Amps also have serial numbers. So the contents of the van w(sh)ould have been recorded.
Pleased he got it back. For all the misty eyed romanticism over it's purchase, the real reason was strangely omitted. In 1961, if you were left handed, you were shit out of luck when it came to asymmetrical instruments like the developing field of electric guitars. And even less so when it came to bass guitars. So basically it was buy the only reversible bass guitar on the market, or ruin the aesthetics by playing a Fender Jazzmaster (or possibly Precision) bass upside down.
The "iconic" role of the Hofner bass is really just an accident of chance.
Ultimately, rock and roll is a chaotic business, and things go missing. There is probably space for a book of famous guitars.
