But if we take that standard as to what is original, then nothing is original.No.You do realize the first one was released on '77, it was original as ... back in that time.
There is a star wars documentary on where George Lucas got his inspiration, he took cues from many other established entities and twisted them together.
Star Wars is about as original as the next remake of Spider-Man.
Not knocking it though, I am a big Star Wars fan myself.
