How the hell does Pantheon have a terrible landscape? It’s literally right next to a forest and a river.
Being next to a water feature or a forest is not having any landscaping. Having good landscaping, especially taking into account other coasters at BGW, includes but not necessarily following terrain up/down natural hills, going through a forest, interacting with a river (mainly following over top in some form), lush foliage surrounding the ride path, etc.
Pantheon is your standard parking lot coaster in that there is flat land with little to no terrain interaction. It doesn't go through any forest area. It would be very unexpected for them to actually do anything extensive landscape wise.
