Should new fans watch the first two films and then all the episodes of the cartoon Clone Wars, before watching the third film, the Revenge of the Sith and the OT after that? I think not knowing that Anakin becomes Vader might be better. Not knowing that Luke and Leia are sisters until the sixth film might be better. Not knowing that Luke is the son of Vader until the fifth film might be better. Maybe new viewers won't realize that Anakin and Luke both have the same last name. It could be a common last name like Mr. Smith.
