I was 4 when I saw ANH for the first time, but I don't remember it at all, and I was 7 when I saw TESB for the 1st time. I have distinct memories of Vader revealing himself as Luke's father. It's one of my earliest film memories. My wife was also 7 when she saw ANH for the 1st time, and she loved it. Watching those films at such a young age left a big impression on both of us, but of course, we only saw the OT when we were kids. Younglings nowadays have an opportunity that we didn't. They can watch all 6 films while still really young. I'm sure a part of my deep affection for SW comes from my childhood exposure to the films. For me, SW is a little like Christmas from my POV; it's for everybody, but kids most of all. I'll never get to know what it's like to watch the PT films or even ROTJ as a really young kid. Still, I'm interested what film from the series children around 7 or so and younger like the most. I'm also curious about the reasons that make that film their favorite. What especially makes me interested in this is that I have absolutely no idea which film kids will generally pick the most.
