The "point" of this expansion always seemed to me just to get some additional rides in the park to up capacity prior to SW being built. I don't think either of the TSL additions is expected to be a "draw", just that they would add more things to do.
That said, I think they'd be better served by dropping the coaster and adding two rides in its place (preferably some dark rides). It takes up a lot of real estate for a relatively short, limited capacity ride while the park needs multiple additions to really round things out.
As many have mentioned, a larger more fleshed out Pixar place would have been a better addition to DHS than a sparse one IP land like TSL. Of course, when TSL was announced, it seemed like an additional IP land (apparently Monstropolis) was also being planned, so it made more sense for a land based on exclusively on Toy Story. Since that land is seemingly off the table, it would be nice if they would revisit and expand the idea for TSL.
