Only problem with that video is it had Adrian Chiles in it, and I find his monotone voice annoying.
I don't really like or dislike any accent per se, usually any accent can be fine but turn bad when it's taken to a certain extreme. For instance I like Billy Connolly's strong accent, but I can barely stand Kirsty Wark's accent. But then there's an element of personal dislike there for Wark as a TV presenter, a la Adrian Chiles so maybe that's part of it as well.
