While the production quality of DoccGero's Lab's Youtube video is poor, and Docc sounds drunk, he hits on an important fact: Return of the Jedi pathetically "pandered to children". It, not the horrible prequels, was where George Lucas's STAR WARS went off the rails. Docc goes off on ewoks, Emperor Palpatine's shallowness, and Darth Vader's lack of integrity as a villain.
It is the film in the original series that I like the least.
The thumbnail image for this post is from this review of another horrible film from the STAR WARS universe, An Ewok Adventure.
