Does it matter?! Do people watch EE just sooo they can pick out these things? Its a soap, for various and obvious reasons, its not going to be completely accurate/realistic..... I think it manages pretty well overall to balance entertaining its audience, with the level of realism it includes.
I watched Emmerdale the other day and its more like a panto/carry on film these days, yet no one picks that soap to pieces, probably cause they would be spending soooo blooming long doing so. Its a shame EE is the whipping boy of the soaps.
