I guess there are several things that make this a tough sell for some Disney fans
1) The best ride "in" Toy Story Land isn't often mentioned in these updates and is rarely pictured -- the currently existing TSMM
2) Slinky is a minor coaster with a cute theme (Barnstormer).
3) The alien saucers are a dressed-up spinner that, minus the theme, you find at any carnival
4) The toy theme, while wholly appropriate, looks a little cheap (trying real hard not to summon images of DinoLand U.S.A.)
5) It badly needs one more ride or show because the "land" looks sooooo small!
I have kids in/near their teen years, so at first glance this amounts to the addition of a cute little coaster and a throwaway in a nicely themed garden behind a ride we already visit.
