I was nine years old when ROTJ was released. At the time it just meant more Star Wars, more TOYS! I loved those breakaway Speeder Bike vehicles (even if the action figures sat weirdly on them).
ROTJ has always been strangely inconsistent, and perhaps this is because of the struggle between what Lucas wanted and Marquand delivered (didn't Lucas also have this problem with Kirsh? Control issues?). TESB turned out to be the best of the three movies, however.
There are some great scenes in ROTJ, though there's also some lazy acting and cheesiness going on in many scenes. The visual effects are great throughout. The last third's editing has always bothered me. Those fantastic space battle scenes are intercut with the less interesting though sometimes humorous Endor scenes, and I often just fast-forwarded through the Ewoks to the Millennium Falcon parts.
It's hard to feel hate for ROTJ. It was the final act of the story at the time, and it still completes the Original Trilogy despite its flaws.
