It's set in Edinburgh so I watched it with closed captioning on because even I, Commonwealthophile that I am, had trouble with the accents. For example, last night a woman leaned over a balcony and yelled down "ish nae mack globby bootch scat fel mart!" which the closed captioning informed me was "if you don't move him from here, there's going to be murder". This was, actually, what convinced me to turn on the closed captioning. I couldn't decipher what she said after three boop-boops back with the TiVo so I admitted defeat.
Anyway, foreign language issues aside, it's brilliant. Rebus. Here endeth the rave.
