It's funny that you post that pic because Return of the Jedi is literally one of the most spoiled movies I've ever seen in my life. I was so ravenously hungry to know how the story ended after waiting three years since Empire that when one of my friends saw it before me I literally said, "tell me everything, tell me absolutely everything!!!" And then he proceeded to literally spell out the movie scene by scene. Of course years later it hit me that "what the hell was I thinking" but honestly at the time as a kid those movies might as well have been real world events where I just wanted any info regardless of how it was presented.
Kind of like if Russians invade America and someone knows something you don't go "well I'll wait for full coverage on the news tonight" no you're like "tell me, tell me what's going on!" And at the time hearing about it was almost as exciting as seeing it. Not ready for the burden of avoiding spoilers was my 9 year old mind...
But thank God that didn't happen with SW or Empire and I got to see those movies cold. Phew.
