Yeah I know what you mean but I feel like I have to have seen them all, also so I can discuss old series with people too and decide who my best housmates are etc.
I think we should watch BB1 UK after BB15 is over tbh, the episodes are short (even shorter than BB3) and I've always wanted to watch it but can never be bothered. There's also a mixed race girl in there who is like a bunny boiler or something <3333
