Nice review that pal.
Not a nit pick, well kind of a nit pick but they only thing I found odd about the film was the use of the word "soz" in the early opening sequence. If you had said soz to me in nineteen seventy something, I wouldn't have known what you were on about.
I smiled when I read your comment that the drug taking was not over done. I say this as I thought the drug scenes were ubiquitous and omnipresent. Though again and as you say mate, we know the reality can be not too dissimilar perhaps on occasion. All about going out and making sure you're gonna have a banging good time!
I do think a certain amount of slack is admissible and licence granted with regard to exactly what was was played and when etc. I don't doubt I'd experience similar situations when I win the Euromillions and make a film about the 100 Club, starring Johnny Depp as 'Simsy' 'Not coming to a cinema near you'..
