:Sorry, it's just when you were saying how we'd be playing into IU favouritism I was like "That isn't what I want."  Oh, and... *guilty look* I may have added a lot of IU crap to some articles.  But that was before I learned the rules, kay? ;) And I was only following others' bad example. By primary sources, I meant cast & crew interviews, not drawing personal conclusions from the show. 

 :I get your point about the analogy.  The Buffy analogy was kinda flawed because Smallville is a total 100% reimagining of Superman, set in a parrallel universal from the comics.  The Buffy comics/novels are meant to be set in the same universe as the show, it's just snobby fans don't count them because they're not by Joss Whedon (who also dismisses them).  I personally count some of the non-canon stuff if it's good enough and in continuity. As for the film, it's in loose continuity... the script is more or less canon, before the crappy director turned it into a mess.
