Agree - it's probably the only BBUK to have little 'Storylines' within it.
The rest usually just blended in together or every other series had one thing that it was known for.
BB5 - Evilness
BB6 - Bitchiness
BB3 - Division
Some series [like BB11 and BB9] would change so much that at the end it seems like a different show.
But yeah I agree BB10 had so many little Soap Opera Storylines going on like Sophia and Sophia's feud, Kris and Sophie's 'romance, the Marcus and Sree feud
, Freddy being picked on constantly, Siavash and Noirin kissing, The Newbies coming in, Rodrigo and Charlie etc etc
It goes on and on - but it was like one 'story' came to a good ending and another plot would begin straight after that usually kept us hooked.
