I know I know it was a good ending but sincerely it was awesome. I love when a movie ends on a terrific dark nature but this time I was impressed with Darth Vader turning against the Emperor I really stayed astonished. The anguishing sequence in that film was when Luke is tortured and defeated by the Emperor/Darth Sidious. He is about to be destroyed when Darth Vader, Dark Lord of the Sith, eliminates his dark master. A nice sacrifice. The cinematography of this film is impressive. I was surprised with all the vessels of the Rebel Battle ships and all Imperial War Ships and Super Star Destroyers. I loved the new race they brought on screen the Mon Calomari, the ewoks, the sullesteian (Lando's co pilot) and many more... Most of my favorite scenes are in that film:1-When Vader destroys the Emperor and is fatally wounded. 2- When Luke sees the spirits of Obi-Wan and Yoda and then it shows up Anakin Skywalker (Sebastian Shaw)(the greatest scene in Star Wars) 3- When LEia slays Jabba strangling the Hutt crime lord.
I personally like the script and the battle of Endor presenting a ground and space combat as well the best duel of Star Wars between Darth Vader V.s Luke Skywalker on the Death Star. Post-script: The scenes with Leia in the slave bikini are memorable. 9/10.
