A couple of observations:
Compared with the snail-like pace of our modern soaps, events in PCBH moved at warp speed. If you missed a single episode it was sometimes difficult to figure out all that had happened.
As far as I can recollect there was very little reported action (one character telling another about something, instead of actually showing it). In PCBH if something important happened inside or outside of Wentworth we nearly always saw it. The only obvious example of reported action I can think of was the death of Bea Smith.
