I don’t doubt that Motocoaster or Shockwave fit the themes that they were going for when they were built, my point is that those themes don’t fit into the general aesthetic of their areas, or the park itself, anymore. I’m struggling to think of the right words, but they’re not as ‘polished’ or ‘timeless’ as Dreamworld are going for. Flyer’ll still be an inoffensive ‘classic’ themed ride in 20 years time, Taipan & SV’ll still be ‘modern/bland’ & inoffensive, Rivertown’ll still be inoffensive ‘jungle’, etc. But Shockwave & Motocoaster are showing the outdated ‘grittiness’ of their theming, and they’ll continue to do that as time goes on, unless something changes.
Bear with me here, cause I really don’t know if this’ll make any sense at all, but I kinda see it as most of Dreamworld’s trying to be like a halfway decent Samsung Galaxy/Google Pixel phone. Maybe SV & ST are a newer iPhone, and Wiggles/ex-KFPL are a cheaper, budget, ‘babies first’ phone, but they’re generally just similarly inoffensive designs. Then, Motocoaster & Shockwave are more like an old Motorola w/ a sliding keyboard. Yeah, they worked when that was the norm, and there’s people who still prefer their look to that of what’s currently popular, but they’d generally be seen as outdated & in need of an upgrade.
