I've always thought it to be a slope re the Watershed. What they are saying with the 9pm watershed is that there won't be anything explicit such as nudity, graphic violence shown that non adults (so that is everything up to 16/18) might not be okay to watch.
But that is not the same thing as saying that everything showm up to 9pm is fine for children of any age to view, especially without adult supervision. When Daytime Television started properly in 1986, they were very careful about what Soaps to buy for it as they knew children and teenagers would be watching it, perhaps on their own so it would have to be less offensive than an evening Soap. Compare Neighbours to EastEnders in the mid 80s - which is the harder in content, even if not explicit and that is because they expect a younger audience at 5.30 than at 7.30 - indeed they edited Neighbours at points because of its timeslot here when they wouldn't if it had been shown after 7pm. OfCom have rejected complaints about Hollyoaks by saying that children should not be watching Hollyoaks and if they do, that is the parents decision, not the makers fault.
Even something like Doctor Who, which is certainly classed as 'family' entertainment, they will transmit some episodes which they consider more disturbing later in the evening, though still not past the 9pm watershed, to indicate that younger children or even teens should not watch that one and they do expect parents to judge as they know their kids and what they will understand, perhaps be scared by.
I have friends who won't let their 12 year old watch any of the evening Soaps, especially EastEnders. They don't consider it suitable for her.
Re teenagers in the show. Yes, there is a place for them, i consider it to be a generational/community Soap so all aspects of that should be represented from kids up to the very elderly. As somebody said, teenagers have always been a part of the show and that should continue.
However, i don't want to get back to a situation which we had a few years ago (during Kirkwood's era I think) when we had about a dozen characters under the age of 21 who were extremely prominent and only 3 characters over 55.
I don't mind Shakil as a character, i just think the actor is very limited but he might improve.
