Kinetic Cajun, I would appreciate it if you would stop arguing over EVERYTHING for no apparent reason. I mean... are you honestly debating the universal relevance of rational thought in a thread that was intended to discuss the relevance of Zelda? Why?
When I clicked on the OP's thread, and after reading his opening post, I said to myself, "yes, Sheik has lost relevance to Brawl at this point; he's right." HOWEVER, when someone else said that, "the only thing that really makes Zelda an interesting character, the only thing that differentiates her from Peach, is her transformation," I said to myself, "wow, you know, he's kind of right! Zelda by herself certainly isn't overly interesting." And when the major opponent to Sheik's continued inclusion admitted that he "was not a true Zelda fan," well... it all clicked.
To me (and this is MY OPINION), if the Sheik/Zelda relationship is altered infofar that one does not exist or they exist entirely separately, then the controversial appeal of the ZELDA character SPECIFICALLY loses appeal. In the games that bear her name she is often a boring, token princess character. The only games where she ever had an interesting impact on the game (IN MY OPINION) were in OoT and WW, Wind Waker most of all. Not because she wore other costumes, but because the directors of the game (Aonuma and whoever) saw fit to give her an actual personality (again, much moreso in Wind Waker, I'd argue). My point is that Zelda isn't an interesting OR popular character by herself. The IDEA, the PREMISE of ZElda is interesting, however, the EXECUTION itself was found wanting, even in TP. Perhaps even ESPECIALLY in Twilight Princess.
Now then. Kinetic Cajun, it would be wonderful if we could continue on without any more immature, underhanded posts.
EDIT: Actually, I'm a HUGE fan of Midna. She exibited the greatest range of emotion, character depth and personal growth out of, perhaps, any other Zelda character before or since. Gannondorf from Wind Waker is the only other example even worthy of being considered a "well-developed character," IN MY OPINION. I'd love to have Midna, and, hell, WIND WAKER GANNONDORF in Brawl over any other Zelda character. Maybe even Link. But that's just me.
