I never really form an opinion on the first few days of a celebrity show, or weeks in the case of the main show. Just for the reason you have pointed out about the dynamics changing.

It take all the house mates time to settle in and show their true self. At the start they some are to concerned with making friends and being on their best behaviour while others just seem like wall flowers. After a while they change and the real people start to appear as they drop their guard.

It's at this point the programme gets interesting.
