I have absolutely zero problems with Frozen taking over Maelstrom, but then again I had no emotional connection to it whatsoever. Toy Story Land, while it won't be a theming masterpiece (with that IP, how could it be?), but the Slinky Dog Coaster is more than it appears on paper, and at least it'll be something different that we've never seen before. So many look at the images released by Disney and think, "Well, it's just the baby coaster with a themed ride vehicle," when in reality it's more of an outdoor, less intense, RnRC with AAs, not to mention the queue will apparently be a sight to behold.
As for NFL, it's all about perspective, in my view NFL accomplished its goal very well. My youngsters absolutely love 7DMT (in their top 3 rides), and I know a lot of parents who say the same. Obviously there is more potential with anything you come across in life, but I'm one who sees the glass as half-full, not half-empty, if you know what I mean.
