I love PB, but it is soooooooooooo drawn out, just like LOST.
Yes, the ending was left open ready for series 3. I didnt know there would be a series 3, until T-bag rattled off at the end!
I would love to NOT watch the oh so drawn out series 3, but get a box set and watch it all in one go. Now finding time to do that, would be like finding time to have a cup of coffee in peace....or going to the loo with out an infant in tow..... just aint gonna happen! LOL
