The main show really needs some work, less flashy effects, less TOWIE, less of a magazine format.
Have to say the live shows have improved vastly this series (bar the live pleas to be kept in), my only issue is Brian, he really needs Emma presenting with him. I really would't mind some elements stolen from the new BB Australia series such as the points system of nominations, housemates have 5 points to allocate to those who they want to nominate. The points can be split 4/1 between two people or 3/2, they're done semi face to face in a glass sound-proof chamber where the housemates sit behind them. Also could borrow the no-outside contact rule and properly strict punishments!
For the whole approach towards the show, it needs to go backwards to go forwards. After a good start I completely lost interest after a few days (again) because it was just annoying to keep up with. BB works better when it is completely stripped back. I don't mind the odd bit of editing when necessary (e.g. nominations, to speed up tasks etc) but making a montage out of the smallest thing (such as getting up) is just silly.
The live shows have also been taken too far and are overproduced to the point where they just look tacky and cheap. Again, they need completely stripping back and going further than your suggestion, I think Emma should take over completely. She is very similar to Davina and that is a figure that has been lacking for quite a while. Emma also has a more robust interview style.
I also feel that with Channel 5 wanting younger people in the house, they're completely ignoring what viewers of the show actually want. The winners of the first four Channel 5 series' were all the oldest. The winner of the one just gone was one of the oldest, with the combined age of the top 3 well over 100! If that isn't evidence enough of what viewers want, then I don't know what is.
