Forgive me if I seem pedantic but I'd usually expect so see some reasoning behind a statement like "Dundee is the dullest, deadest UK city I have ever visited", so sweeping and damning as it is... What exactly is it you don't like about the place, other than it's public art (the only element you mention). For want of further explanation I'll assume that your view is a kneejerk reaction to one, possibly two visits to the city - probably a dull, rainy afternoon, midweek, scurrying from the train to whatever engagement you had and back again. I'd like to think that you had time to explore the entire city, its universities and surrounds but somehow I don't think you did... That is the assumption I'll make until I'm told differently.
And by claiming that dundee is "dead" you also implicate it's people, suggesting some lack of energy, forward thinking or movement. The truth is that Dundee has more life about it than many places I've been in Scotland and further afield with more dynamism than cities that are much bigger and have more wealth.
I'll concede that Dundee needs further development and change, but only to consolidate the advances that have already been made, not as some sort of alternative to what's already there. It's not a "rescue plan" or a "solution" - as Dundee is one place that has already rescued itself from the problems it faced ten or fifteen years ago. It's the nescessary and logical expansion of a city that is on the up.
