TV soaps don’t change much.
Christmas 2013 and in Emmerdale there’s the Alicia and David wedding storyline. Fast forward to Christmas 2014 and it’s the Andy and Kate wedding storyline.
These “serial dramas” don’t even bother attempting to have an original story at Christmas, do they?
The same principle applies to Coronation Street and East Enders: the same themes over and over again.
