Robocop 2 was butchered, he took plenty of things out of Frank Miller's script (long before Frank moved from writing and drawing comic books like Batman - The Dark Night Returns to making movies like Sin City and 300). He claims it was a bad script to begin with.
I used to agree with the meme that Empire Strikes Back was the best of the Star Wars films. After Lucas messed with the series and filmed a trilogy of prequels, I have to disagree.
Star Wars I (chapter IV) can stand on its own. Yes Vader gets away. Lives again to fight another day as do other cinema villains.
Star Wars II (Empire Strikes Back, Chapter V) ends with an outright cliffhanger, too many dangling plot threads. Hero has his hand cut off. Vader escapes. Han Solo is deep frozen. And you'd better have seen the first film to understand the characters (not so with the Bond series).
Star Wars III (Return/Revenge of the Jedi, Chapter VI) ends with Ewok teddy bear toy salesmen. And if we are to understand the story, it was only the end of the second trilogy, three more chapters will never be filmed.
So what then? Do we watch “Chapters I-III” next ending with the Revenge of the Sith (2005)? That will likewise leave the viewer with an unfulfilled reaction to the series.
But a viewer can enjoy A New Hope and be done with the matter.
Ah, but they will.
They were originally intended to be "The Further Adventures of Luke, Leia and Han" or some such.
George Lucas has said outright that he will make no more Star Wars films but would certainly allow the remaining 3 to be made when the right story and director comes along. I may never live to see them but Episodes 7, 8 and 9 will be filmed.
