While I loved Dinosaur, the pairing of giant creatures and speed is counter intuitive. Grandeur needs time. Even the Yeti is flawed by concept. If you're going to go big, you need more than fleeting seconds. I dearly wish they would actually commit to a proper land of prehistoric giants, but things as they are have me okay with the coming changes.
The Yeti is sort of its own thing there - you're meant by the end to wonder if you really even saw what you just saw. Being a mythical creature you're supposed to feel as if you've only gotten a fleeting glimpse to take away, lucky to have seen it at all given that its existence is unverified, but that within that glimpse he was a fully believable as a real and ferocious creature. Of course this has been completely kneecapped by the figure's operational status, which is tragic.
Dinosaur takes a different approach, where it lets you stop and see the big bad creature multiple times - but how scary is an enormous, sharp-toothed Dinosaur if you keep running into it and he never seems to "get you"? The speed is meant to amp up the thrill and provide a base level of fear the Carnotaurus can push you over the top from. We do get a brief moment closer to "grandeur" at the beginning with the Triceratops, but it's pretty clear the goal here isn't to revel in the majesty of these creatures.
I do agree that there is a void that deserves to be filled where guests are given the opportunity to take in the sheer awesomeness of realistic, full-size Dinosaurs, especially since losing Universe of Energy. UoE was never perfect when it came to fulfilling that type of experience, but it was something rather than nothing. That Disney wants to divest further from Dinosaurs in their theme parks is such a boneheaded mistake - there's so much creative potential, and an eternal appetite for the chance to see Dinos "for real".
Yes, they have to avoid and compete with Jurassic Park up the road, but given that Universal's Dinosaur offerings fall short of delivering the kind of awe-inspiring experience there's so much potential for, Disney should be doubling down on Dinos rather than throwing in the towel.
