New paint is all good but will still look a mess on the water feature and landscaping they ruined with concrete. It's a shame, if they replaced the trains (even if it means losing a car on each), painted the coaster/area up, landscaped and peppered some theming in, it would actually look decent. I've always thought the pathways going above and beneath the coaster always had potential.
Not sure how feasible new trains would even be, though.
