He's pretty good.
 
I don't mind the Brummie accent, I guess I got used to it when I lived there. I also learned the lesson that identifying a Brummie as a Black Country accent, and vice versa, does not make one very popular.
 
The Geordie accent's alright too, unless it's being uttered by Cheryl Cole when she's *trying* to talk proper
 
For me, the accents that grate the most are the Scousers' and the Mancs'. Of the two, I'd put the latter as the most irritating. Unless it's uttered on Shameless.

It's disgraceful that they've omitted Geordie, easily the most important and prestigious UK accent  
 
I lived on Nantucket for a year. There's a lot of Jamaicans living there and I was struck by how similar the Jamaican and Geordie accents are - they agreed. The way they say their a's as in "place" or "ball" is almost exactly the same. I wouldn't be surprised if the Jamaicans picked up their accents from a Geordie somewhere down the line. 
 
When you've grown up somewhere, your ears get to discern the slightest differences between what to outsiders sounds like the exact same accent. I can hear differences in the Geordie spoken every couple of miles or so, as well as the subtle differences between the male and female forms. Whereas someone from London will frequently confuse Geordie (Newcastle) with Mackem (Sunderland) even though the two cities are a whopping 15 miles apart. 

British Isles as a geographic group of Islands, not a political entity. Great Britain is the largest island, followed by Ireland. Great Britain is called Great because it's the biggest, not because of ego (at least initially)

agreed on that. In Devon, you only have to a few miles to here a different accent, but they all get lumped in with zumerzet and Cornwall.

Except in Torquay where all you seem to hear is Manc and Scouse.

I had cousins in Torquay, spend many a childhood summer on Babbacombe beach. It's a cheap holiday destination, like Blackpool, so I'm not surprised that it's full of Mancs and Scousers

I'm from the North East originally and if you mean Geordie specifically as in the Tyneside/Newcastle accent I think that's an exaggeration though it is possible to place people in the north east generally every few miles.

It's not much of an exaggeration, you hear subtle differences in say, Byker Geordie and that spoken in the West End or the coast for instance. Then you start to hear a milder form of Geordie spoken in places like Heaton, Jesmond, Gosforth etc. Of course once you get out to places like Cramlington the difference is far more noticeable.
