The nation's favourite painting

Offer me a list of "The Nation's Favourite..." (book, seaside resort, love poem, whatever) and I'll rise to the bait, muttering about the pointlessness of the exercise and denouncing the unrepresentative result without pausing for breath between the two. Yet somehow I can't get excited about the news that Turner's The Fighting Temeraire is the Nation's Favourite Painting.
( Despite which, she manages to whip up some excitement )
