Actually, some green light effects (in the transition from sound to sight) and the door out of sound have been deactivated since 2002 along with the usual maintenance problems and old animatronics/ride vehicles/abused 1983 track.
As for the image works, it started going downhill after the loss of Kodak sponsorship (all the shuttered photo rooms). Compared to 2002, it's virtually empty and what's left doesn't work like it used to.
All in all, this ride should've kicked the bucket 10 years ago at least, but here we are.
