Coventry University. Undoubtedly the absolute worst, scummiest city in the UK. It's basically Detroit - complete with being the former home of the car industry but now filled with long-abandoned factories - only pretty much without any redeeming features whatsoever. Oh, and because of its history as a major manufacturing centre, it was I think the place in the UK which received the most bombs per square mile during the Blitz in WW2. Consequently, virtually all of its historical buildings were completely obliterated in the war, and unfortunately the architectural style of the 40s and 50s was to build concrete blocks with no real decoration at all, meaning that the entire city centre is just full of soulless, horrible buildings. It's also basically filled with working class trash. And while I was there, not only was my student house broken into, but my (future) brother-in-law's student house was, too. Kind of says everything about what Coventry is like.
I really didn't have to tell you that, but I really hate Coventry. I don't think I'm capable of saying the word without then launching into how much I despise that city.
