This is interesting.
I suspect most places people don't like are places they built up going in then the 'reality' didn't match their fantasy. That reality unfortunately now usually being a few days of jumping between sights, snapping pictures and moving on. Paris is probably the worst for this. I reckon you could pretty accurately guess who will like Paris or not just by their itinerary.
There is chat here about Barcelona being full of tourists. Having been there many times to visit relatives, I've never really seen tourists there. I guess that's a different part of the city. I've also never really seen any of the sights, and wouldn't know what they were, because we tend just to hang out in their neighbourhood. Same city, wildly different experience.
It also depends a lot on where you've come from. Santiago for instance. The first time I visited Santiago was after 6 months travelling around rural Colombia, Ecuador, Peru, Bolivia and Northern Chile. Almost none of these places had bitumen roads, concrete footpaths, clean anything, internet, sometimes electricity, hot water, heating, cooling, yadda yadda. The contrast with Santiago in a single bus trip was just mind blowing. It's a completely different world more closely resembling Sydney or Auckland than its South American neighbours (at least the parts I visited). So to me, everything about Santiago was staggering and I relished my time there, although it did seem outlandishly expensive relative to where I'd just been. Luxuries like water fountains in parks to enhance the beauty of it, a private spa bath, electric blankets and the like were just unimaginable where I had been for the last 6 months just down the road. Now, had I come from Sydney or Auckland knowing nothing about the rest of the continent, I suspect it looks quite different and I might have even been disappointed! Also I have since visited parts of the city that much closer resemble rural South America. Had I stayed there, my view would be very different again.
The only places I didn't like when travelling were Tangiers and Delhi. Tangiers because I was with a friend who wanted to do the tour thing so all I saw were people trying to exploit me. One day there left me with a sour taste because of the way I experienced it. In Delhi I got ripped off by a tour company in cahoots with the hotel I was staying at. That scam cost me over $2000. Given a large part of my exposure to Delhi culture was a thieving tour company and their hotel accomplice, I basically told everyone never to go near the place because there was no place worse on the planet. Then, had I picked a different hotel to start with, my view on Delhi would likely be completely different.
Some of the places mentioned here and in the article are truly remarkable places. I reckon generally it is almost irrelevant which city names are on your itinerary - they can all be great or terrible. And the final judgment will be based on such a tiny sample of experience of the place that it is ultimately useless to anyone except the person who had it.
