I personally wouldn't do a 5 min departure about Grossman trying to get a BBC deal done having one of the most intriguing characters of all time in Dylan. Even more questionable considering Grossman himself is a producer here, so I guess he is just tooting his own horn lol
Just feels like there was so much left behind that could've make it in the final cut. Although I do think this respects the enigmatic nature of Dylan, people approaches him trying to get answers and leave with more questions.
