Brits in general seem to be on a bit of a downswing in terms of how amazing we think you are. Right now it's pegged somewhere around "you've got as many problems as the rest of us" where before ~y2k we thought the US was some sort of magical fairyland where everything was made of candy.
In Britain, The Guardian fills a political niche quite similar to that of the NY Times, perhaps with a little less stuffiness as it does not consider itself the paper of record (a position traditionally filled by The [London] Times, a more conservative paper.) It also has a tendency to be less deferential than the NY Times, but that simply reflects the UK press in general, where politicians are widely regarded as being only marginally higher than scum.
I think if you were to ask the self-anointed 'elites' in the Guardian editorial room and then the British people what they think of America, you would find somewhat divergent percentages of pro- and anti-...
As an American, I love Britain and believe in the Special Relationship, as much as the Guardian (and occasionally our current President) would poo-poo the whole thing.
What's with the Guardian and "From my perspective, America's not so great!" articles? Not, like, "how could anyone think that?" but why does it seem to be such a regular feature? I admit upfront my being American may cause me to imagine/over-remember this phenomenon.
