All of the films you mentioned (with the exception of the Godfather) have there own individual discussion areas here on KMC so they are kept out of the main areas, it is then up to each member if they wish to visit those aforementioned areas and as far as i remember the KMC staff do a pretty good job of keeping all LotR, Star Wars and Matrix talk in their respective areas ultimately not exposing non-fans to the hype, so you can't really complain in that respects.
