They could use some of the follow up show to show more unedited footage of the camp.
Not showing unedited footage has made it all seem less immediate and we get less of the atmosphere plus seeing what people are like when they're together but are performing, less. We has no idea who did tasks in camp, this year apart from eg seeing Michael carrying logs and Mel cooking. The jungle and the camp seemed to be being treated as less relevant, this year. When that happens it becomes a bit Big Brother.
Rob Beckett and Joe Swash should go. They're beyond awful. How on earth Rob Beckett got that job is mystifying.
Introduce the campmates with a brief bio, - or ask them, to do it, at the start. - in the camp. It would be interesting for viewers to know who they are and what they've done without having to google them.
Please would producers not pick who they, think should win and then give them more screen time. Let viewers, decide.
Immunity from doing a trial, for a a day after having done one.
Splitting the camp at the start, wasn't a good idea.. It seemed too negative and cruel as a start to the series. Whoever is in charge seemed to go for what they thought would look good rather than being aware of how to draw viewers in and make them relate to everyone and the camp. It was predictable that rightly, the other campmates would get the other ones out so why bother to drag everyone through it.
Overall, watching this series often felt as if it was dominated too much by producers and on the follow up show, by the presenters. It's not about you, guys. Obviously, lots of people working on the show do a great job but there are some, who need to step back a bit and let the show dominate rather than be dominating the show.
It's understandable that some control is essential but when that goes too far, things get too predictable.
