PB was fantastic until the mid way break for S1 where it got picked up for S2, from then on it was suddenly re-hashed to allow for S2, look at the end of S1, it was dire. S2 was OK but started to get rather caught up in its own complexity for the sake of complexity, again it didn't live up to S1, S3 was a bad rehash of S1+2 with little new to offer, even the cast/writers admitted they lost direction and needed to bring it back on track. I just hope the break from the strike will give them the opportunity for one last run to finish on a high rather than pull what was a good show down.
