It's always interesting to me how people people can feel so differently about the same thing. I found Festival of Fantasy to have incredibly catchy music, and I'm not really a big fan of the Once Upon a Christmastime music. My main critique is that the parade seems a little short, but they pack in so much into those 15 minutes that I can let it slide.
Also, there's already a video on Youtube of kid who was scared of the Maleficent float. I swear, if this becomes big enough of a problem that the float is cut, I might just hate children forever.
