I ve added a citation for Epicurus being the originator of the Problem of Evil There s probably a better one available somewhere but this one will do for now Not sure whether you were looking for a cite for the theory as a whole or not I don t see a lot of mainstream media discussion of the alternate ending theory except for maybe this article in The Oregon Herald a publication with which I am unfamiliar but there s plenty of discussion of it in online sources reviewers and blogs message boards etc As such it s not original research but it d be nice to have a firm print citation if someone can find one
