Mine would be...
1) Make the outside crowd/stage area more like it used to be - think BB7. I loved it like that. Simple - just a long path surrounded by a really big crowd and then a little round stage to stand on before walking up the stairs. Oh, and they arrive by car obviously. I liked the big eye they walked out of in CBB/BB12 but after a while it started to annoy me. Don't know why but i've gone off it now.
2) LIVE FEED! I'm not even too bothered myself but if it stops everyone complaining about it then that can only be a good thing!
3) The housemates to actually have a bit of a hard time sometimes. It's great to see them partying sometimes but this series it seemed to be just parties 24/7 and it got a bit boring really. I like to see them work hard!
4) The winner to actually recieve the full £100,000.
5) Make sure Brian Dowling never does that salute thing at the beginning of a show EVER AGAIN!
