I've had the proper stuff in Turkey and it's not sweet, it's not sticky or gooey. The flavour, at least of the stuff I had, was subtle.
Not sure if it was British-made, mind you...
I recall it as being disgusting, but mostly because of the texture. I don't recall it being gummy or chewy at all -- it was soft and didn't put up resistance when you bit into it.
Gotta love the hate that shows up in the food names. Otherwise, i guess we like each other :)
For the coffee thing, it's not particularly any hate -- people just know this coffee for ages, from when they were kids, as the major domestic variety, so they call it like that. The same happens all over the Balkans, they call it X coffee in most countries X. That said, I think it's a general beverage that comes from the middle east / arab countries in general (Wikipedia says it originated in Yemen, existed in Egypt, etc before getting popular elsewhere), rather than something particularly Turkish, just that the Turkish branded it first.
That said, the most common kind has a very thin layer of icing sugar coating. It looks like this: https://i.imgur.com/TeSQuzP.jpg

Maybe misnamed, but hardly the hardly the fault of Mr. Lewis.
