I'm actually curious to know what rides MW or VRTP have let deteriorate? LW was given a refresh by getting a new theme and trains. Both Batman and Gremlins were closed to make way for great new rides, with LT presumably next to follow. Sure, Batman and LT weren't looking great by the end of their life BUT they were at the end of their life, they could have kept them going with less people visiting and let them fall apart even more, same goes for BT which is now getting replaced. WWF just went through a major rehab, sure the lift hill isn't quite what it used to be since the fire but that was a long time ago, and at its current standard all effects are always going to the best of their ability. Anytime something wasn't quite right with Scooby people on here would mention this and it would seem the next time someone visited the problem was fixed. The flooding on SE broke, that was fixed. Corkscrew was given a new lease of life as SV and when problems occurred with that the park spent a considerable amount of money fixing it to keep it going. I've the flume go down numerous times as well for a well deserved rehab.
So, really I'm curious what rides then has the park "let go" to deteriorate, as is apparently their reputation, other than ones that are getting ear marked for replacements?
