What is the most overrated British city you've visited?

I recently visited Bristol for the first time after hearing tons of great things on here. I'm not sure what i was expecting or that maybe i just visited it on a bad day, but my god is was rundown. The harbour side was lovely but apart from that it was fully of empty units, litter, homelessness, lots of angry preacher, horrible 70s architecture, and the whole town centre smelt like weed. Not shitting on Bristol, im sure it has lovely aspects to it, but i was just expecting it to be more edgy, artistic and, well, cleaner.
