First let me say that I cannot believe that this has 1, 2, or even 3 star reviews. The review that mentions him in the same bracket as Michael Mcintyre, & John Bishop, as spoon fed comedy, is in itself a spoon fed review from some one that is up their own a***. I have heard this line from several people now, and it in itself is the epitome of laziness, and as original as "why did the chicken cross the road"; get a life. This is working class comedy, it appeals to the masses, and there's absolutely nothing wrong with that. I enjoy comedy on all levels, from Bridges, to Rich Hall & Ben Elton. There shouldn't be any snobbery in comedy.
I was born in Glasgow, but living in London most of my life I have lost my accent. I have however been surrounded by family members with strong Glaswegian accents, so have no problem understanding the humour. Yes, this whole routine is based on Glaswegian themes, but for someone who is so young (born 1986), it's not surprising that his experiences will be somewhat limited - not very well travelled, no children, not married etc... something other comedians can draw heavily on. This for me was good, as it meant he could go into detail about many things I could personally relate to. He didn't jump from children, to politics, to reality TV, as if just going through a pre-prepared list of jokes.
To try and be neutral, as everyone has their own taste in music/film/art, I would say have a look at some of the clips of this routine on Youtube, and if you think he isn't for you, then don't buy it.
I will say this, my favourite comedian of all time is Billy Connolly, but after watching this stand up it's going to be hard to watch Billy again as he feels slow by comparison. This will be a great addition to my small Blu-Ray collection.
