I was watching this compilation earlier and I didn't realise just how normal it was in Series 1 and 2 to have fights and arguments in practically every episode
Series 1 and Series 2 on their own probably had more arguments than 3, 4 and 5 combined. I also liked that 1 and 2's fights weren't always over love/romance either, they felt like BB arguments with fights over stuff like toast etc.
Last series the only arguments that really happened were to do with love/romance/coupling up. Everyone nowadays is too afraid to ruin their image with the public. They need to start casting argumentative people again that generally dislike living with other people!
