Because it is not better than the other assortment of flat rides, just different rides that are just as lacking in being more than a ride experience. The aesthetics and 'theme' of the land are exactly the same as the maligned Toy Story Playland, but people are acting like it is totally different. The land will also not fill any need for little ones, as the new rides will have height restrictions in line with existing attractions.
This is not about what appeals to me. As far as rides go, Mater's Junkyard Jamboree is a lot of fun and I love roller coasters. As rides, they're great, but we are supposedly talking about a theme park and not an amusement park. This land is a branded amusement park.
