I think it is just Andrew Davies having got very bored with doing straightforward JA adaptations for the BBC and (accoridng to one newspaper) sexing it up for ITV. JA meets love island.
The problem is there have been so many tv adaptation of JA and others, that something like this just seems a parody.
To quote a newspaper reviewer, in going for the bling zing style it just doesn't have any of the JA quiet observations and implied content behind polite conversation.
Or maybe its just JA meets Beecham House.
