we had been looking forward to this programme but were very disappointed with it. It seemed to jump from one thing to another, and the voices were out of sync too. We found it very 'Blue Peterish'' as though the viewers were childrenbeing talked down to. Don't think we'll be watching again.
You didn't even notice that it was called "Big Blue Live".......! (I didn't see it but expect that the sync problems were due to it being a live transmission from several thousand miles away while also in HD?)
