How many do they really need?

I know that their car is big (and red) but, as I passed the sign that said "500 car parks for The Wiggles this way -->", I wondered if they really needed that many.

I have waited so long for this series and finally it was here. And I was so disappointed - I had always worried that, in the midst of gorgeous location, great special effects and pretty actors, they would forget plot. I was wrong because plot made it - but characterisation didn't. A less engaging bunch of people it would be hard to imagine. Stephen Lang and Jason O'Mara are so wooden it is painful and I am well over the bunch of teenagers that appear to be sub-plot. Bored now!
