The irony is if Lucas stayed with the supposed Kurtz Jedi version which is not 'as happy' as the movie ended up being, I probablyl wouldn't have liked it at the time when I was 10 years old in 1983.

But the movie would have aged better, and the overall story arc from SW to Empire to Jedi would be a much better story years later. As a kid, I wanted all the heroes to survive and have one big picnic at the end on Endor, but seeing the movies now, a bittersweet ending that has alot of subtext would have made Jedi and the Trilogy that much better today.
