I had read The Hobbit before I saw the LOTR films. It was peculiar to me that the tiny plot point of Bilbo's ring was expanded into an epic trilogy. It irks me when minute points in a story are later so elaborated upon, when the story the point originated from worked so well as a stand-alone, and the point as a minute point.
Elan Sleazebaggano ("You wanna buy some death sticks?") in Attack of the Clones was given a small, passing scene played only for humor. The Expanded Universe took that passing scene, took the character, and elaborated on... pointlessly... just so people could know more about the character created only for passing humor.
Am I the only one annoyed by things like this? It's cheap.
