Thing is, as mentioned, EE have had younger cast taking lead stories, such as Sonia's Surprise Pregnancy for example, & that was good, but it seems recently than any soap (apart from Hollyoaks) who tries to give younger actors lead stories end up being criticised.
The reason I think as to why younger actors are criticised (& this was a good point in EE) is because the actors they employed were 'Picture Perfect' if you like, with six packs, & perfect teeth & tidy hair that was never out of place. When I asked a few older people what they thought about EE during this time, they said they refused to watch it because it wasn't EE, it was a parody of Hollyoaks & it had become some sort of fake foreign soap opera with picture perfect actors. They were right. Soaps were supposed to represent real life, not become American parodies with beautiful faces running the show.
EastEnders for a time became like the X-Factor, the reason the viewers were tuning in was to see scenes with Joey Branning Running or Tyler Moon with his top off. It wasn't about the stories, just the beautiful actors.
