The mistake was billing this as a remake of BOBW,,it's not.
Anyone who remembers the original will be disappointed. That contained a detailed character study of the the four main participants. This has been pared down from it's original 7 episodes to only 3..you can't lose 4 episodes and still show the the depth of character that was so important to the original.
I can still watch this and forget the original, but some things continue to annoy me. For example, I don't see why the Gavin character was changed. In the original, he appeared older, he had a certain charm, and was Peter's intellectual equal. In this he behaves like a petulant child, but still somehow has powers of seduction that are beyond comprehension.
They also seem largely to have abondoned the sado-masochistic angle, there have been a couple of references from Gavin saying Prue had "wanted It"..but it was important to the original plot, Pru was no innocent in the first series !
Of course, there is one more episode for them to explore the relationships further, and perhaps explain the strange attractions and the motives behind their actions.
