Ok apologies for what might quite possibly be fever/medication induced bilge here, but whilst suffering in my sick bed about why Eastenders of old felt more compelling viewing. I think it's because they used a more sociological style of storytelling, with people deeply rooted in a place and time with 'world building' that doesn't happen now. Detailed family conversations about a turkey, or about changes in the wholesale price of fruit and veg, or whatever humdrum family or individual lives were focused on. This had the effect of making you invest more as you wanted to go into that world and 'meet" the people you liked, loved, hated, or judged of an evening.
This approach also invested more into character development because the everyday banalities are what life is. For example an episode I just watched devoted a big chunk of the episode to building up a picture of Sharon and (brother) Dennis's relationship- he made her a delicious Christmas breakfast and she went on and on about how horrible it tasted. You've given me food poisoning Dennis! Look, the salmon was out of date. Then going to A&E and her complaining about Dennis to reception then refusing to let him sit next to her. OK this was part of a plot line building towards her pregnancy but I feel like modern EE would have covered it in one min flat, first with her saying she had food poisoning and needing to go to A&E and then her being given her results, losing out on the character development of their bickering and world building and minutiae of drunk man knocking over the Christmas tree and reminding us all of the times we've had to wait in A&E and what a nightmare it is.
That's also I think why the Phil storyline has been so excellent, because the writers have invested proper time in showing us a man with spiralling depression, often in benign moments like him walking out of social engagements, until the deep focus of the last couple of weeks on his state of mind.
As a PP said soaps are about the mundane bits of life as well as thw dramatic, so I'd like to see EE invest more in character development than just having interactions be about moving on a plot line or the odd comedic moment.
Here endeth the treatise.
