^ Yep.

There's a lot of "taking his word for it" in ROTJ. We take Yoda's word for it that Luke's training is complete, even though he was a novice when he left Dagobah in the last film, and learned little of value skill-wise after fighting Vader. We take Obi-Wan's word for it that he was telling the truth to Luke in ANH from a certain point of view, and that Leia is Luke's lost sister.

We have to take the film's word for it that Ewoks could make child's play of storm-troopers with little consequence, that the Empire would leave the Death Star II's most vulnerable point so accessible during construction after what happened last time, etc.

Suspension of disbelief is challenged repeatedly. In the previous two films, I personally could get lost in the universe while watching. While watching ROTJ, however, it's easier for me to get lost in the script's laziness.
