Personally, Xander was for the most part the one solid character. With everything that happened, yes he changed slightly, but he never let it change him so completely he lost himself.

Buffy at one point becomes a drunken slob, Willow turned evil, and who was there to save them......Xander both times. Without him and his character being exactly who he was, Willow would have been lost and Buffy a cave woman.

Every friend group has that one person that just stays who they are no matter what. Think about it, even in yours who do you lean towards when times get hard, that friend you know that is just so solidly themselves. That was Xander for the scooby gang.

I would have preferred they use the Tim Curry Pennywise in the images. I found him much more fearsome than the newer guy. I seriously got absolutely no chills from the new version, where as the original left me with a definite clown phobia it took me years to get over.
