I personally feel that the best thing the show can do is to lose all the channel 5 connotations and start from scratch. New House, new presenters, preferably a live feed option and less of the media-savvy housemates.
Hopefully big brother will get back to us, once he’s been on a well deserved vacation.
It would be difficult for anyone to have more than an emotional connection towards the current house and set, but its demolition does dash hopes of a return even more so. Bringing back the show would be a risk for any network, the added cost of building a new house can only be a negative.
There’s a lot the show could ditch from its Channel 5 era, but I think not having Emma and Rylan - particularly Emma as one of the UK’s top presenters - would be a massive mistake. The two of them, just like Davina, have a lot of love for the show and their enthusiasm for it translates in their presenting, imo. I personally think, unless someone was able to persuade Davina to return, you’d need Emma and Rylan to help bridge the gap between the show’s history and hypothetical return.
