Soaps have to exist 'in aspic' as the producer refers to EastEnders.
Any soap, from any country, falls apart under the slightest reasonable scrutiny.
The level of drama that affects the small locations of any soap would attract national headlines in 'real life'.
The large number of deeply unpleasant people that populate Albert Square would mean that anyone with a modicum of sanity would be running for the hills in less than a week - not remaining there to become embroiled in the nasty small-minded pointless endless petty minutia that makes up daily 'lives' in Albert Square.
So I would suggest they leave well alone - and leave soap islands where they exist, in the imaginations of writers and viewers alike. It's not broke, don't fix it.
