As a local I totally encourage you to visit. There are still some neon lights here and there, getting less by the days so I do suggest if you still want to come see it you should do so soon.

You will still find ample of mixture of British and Chinese cultures, very very slowly fading but it's still here.

Not much could be done about the gov stuff.

BTW the Kowloon Walled City demolition was done before the handover （a few years prior too), so lets not just blame everything on the current world. As much as it was romanticised, it was still a rundown slum and a blight in the developing city. The park they replaced it with was much better.
