The second death star is fine and the insanely good space battle and throne room scenes (both still never topped after 40 years of trying) wouldn’t be the same without it.
Agreed. The battle of Endor still hasn’t really been topped.
ROTJ has some amazing stuff in it, especially the throne room and Endor space battle. I don’t mind the Death Star 2 either.
Still I think ROTJ has more flaws than the other OT movies. I don’t like how the Jabba sequence is disconnected from the rest of the film, in the sense that nothing in Act I directly causes or leads into the events of Act II (apart from the very broad fact that Han is now around). This is a subjective complaint; most people probably don’t mind. For most of my life I didn’t mind either. But after I started to appreciate how tightly written both ANH and ESB are in terms of Event A leading to Event B, the script for ROTJ seems structurally flawed to me.
The middle act in the Endor forest also really stalls the film, particularly after they meet the Ewoks. For me, the scenes in ANH where C3PO and R2D2 slowly wander across the desert are actually very interesting because Tatooine seems like this mysterious, alien place, and the Jawas as alien tech scavengers are an interesting and creative concept. But Endor is just so mundane - the California redwood forest, while theoretically beautiful, comes off as aggressively bland and often feels like a fan-fiction location. Way too much time is devoted to the Ewoks capturing our heroes, the gimmick with C3PO as their deity, etc. I think the whole Endor sequence really needed to be streamlined and made a bit more visually interesting - perhaps a better cinematographer would have helped. And yeah, the Rebel commandos really needed more screen-time and involvement in the battle.
