I get they tried something different and unique from the other areas, but it doesn't work or feel like a fleshed out, themed land at all. That ugly concrete curb at the edge of the water throughout is hideous and breaks that immersion of being in a natural park. Then aside from the restaurant buildings that are mostly nice looking enough (not counting Meteor), the structures are just so plain with so much bare concrete, in addition to the super wide open concrete walkways. From the entrance to Atlantic is mostly fine aside from that ugly water's edge, but everything from that point to the back of the park is rough looking. Much more 'man-made concrete environment with better landscaping' than 'themed park where citizens called Celestians live and travel through'.
The park absolutely doesn't need more coasters though. It'll have 7 after the two new additions in Dark Universe and Potter.
