But it's not the same anymore. Basically, the only way to get the same effect is to rent a cinema every three years. Actually, you'll only need to do this twice in three years to get to the "bombshell". So, start with Star Wars (episode IV should certainly be referred to as "Star Wars" in this instance) when your children are about seven years old. Slowly introduce them to A New Hope toys. There weren't very many of these toys back in the day, a pretty small variety, actually. Of course now these toys will be competing with TV, games, music, etc in a way that they did not back in the day. A couple years after seeing Star Wars you can start "teasing" The Empire Strikes Back. Rent the cinema again and hopefully they'll always remember their childhood shock. Now, if you feel really cruel you can make them wait another three years to see all the cliff hangers resolved but that would be really mean. That's if they even care or haven't downloaded 1080P torrents while you weren't looking!
I was fortunate that when my daughter was about 9 the Special Editions were making their theatrical run. Now, you might want to hurry up and have kids now as I believe Lucas is getting geared up for a 3D theatrical run. I hope he sticks to the 4,5,6,1,2,3 order. I also noticed that the bluray 6 pack is on Amazon although I don't recall the release information.
