I'm one of those people that believe it. And it's not 'lame' persay... I think it was very poorly executed. Otherwise there really wouldn't be any threads like this. But hey... here we are... There's potential for this roller coaster but it just doesn't catch my stomach and it tries to compensate with over the top visuals to cover up a story that has a great setting but unattachable hollow characters, save Squall. Don't hate me.

Now the R=U adds something like the story of Darth Vader to it. If Episode One was your first Star Wars, then one can see how it's hard to imagine how this innocent boy will become the scurge of the galaxy. Much like R=U there clues that hint to it, and it's not that there are 'facts' against it that hurts it so, it's that there support for it are pretty null and void.

It's almost like a questionable intentional/unintentional 'easter egg' after the story ends. Because whether Rinoa becomes Ultimecia or no, Ultimecia still exists in the future at the end and can possess her... Or can't she?
