It's certainly not realistic. If everyone behaved like they do in Eastenders we'd all be killing each other.
I'm not a fan because of the way the characters act towards each other, but it's probably truer to many people's lives than the things I like. Which is fine.
Lots of people like it, so fair enough.
I think the bit about it competing 'too well' with alternatives could indeed be part of the justification for tearing apart the BBC as the Tories, apparently, will do once they get their grubby hands on power
