I have to admit, I’ve been in the “ROTJ isn’t good” camp for a while now… but lately I rewatched it and I remembered how good it really was.
It’s the type of movie that sounds bad on paper but when you watch it it somehow works. A lot of moments require you turn your brain off (Luke’s plan, the Ewoks, the 2nd Death Star etc) but these all lead to payoffs that make it worthwhile (unlike some other movies cough cough). It’s also probably the most emotional of the Star Wars movies. Possibly tied with Empire. But you can really feel for Luke’s struggle with the dark side in the final confrontation, mirrored with the complete hopelessness of the situation outside. That’s something neither the PT or ST ever come close too, and boy did they try.
I wouldn’t call it a good “film”, but it is a good “movie”, and a great “blockbuster”.
