Watch the show before you piss on it, Bring Back Star Wars is all about the original trilogy. The idea behind it is to meet the original cast and to talk them into attending a reunion party. It is all about the good bits of Star Wars. If nothing of Star Wars was made after 1983, this documentary would be exactly the same as it is now.
It's good stuff sky, trust me, I am usually as pessimistic as you are about anything new with the name "Star Wars" on it.
