I can only speak for EastEnders as I don't watch the others but I'm actually more interested in the other side storylines, such as Charlie/Yvonne/Dot and Shirley/Mick than the Lucy Beale murder.
I am more interested in EE picking up the Charlie Cotton SL as I have lost interest in the LB murder (to slow a pace for me and I finding myself care less and less about who killed her and why)
Hollyoaks - I really dont care who killed Fraser! I am far more interested in the Maxine/Patrick domestic abuse SL, John Pauls rape SL, BLessings SL is an interesting one too
I chose EastEnders, as the Lucy storyline is generally why I tune into EastEnders. I prefer both Emmerdale and Hollyoaks over EastEnders, just their other storylines
The week Tina was murdered was fantastic, but since then it's just gone downhill again...
I have no intention to watch Hollyjokes as I think it's horrendous
I've only seen bits of Emmerdale because of the World Cup (I don't watch Football)
I'll go with 'Who Killed Lucy?'
