I can tell that some of the effects were fixed during closed season this year. Some of the drools are looking better than in the last few seasons and some of the effects have clearly been fixed. The things that haven't though really stand out. The screaming room is absolutely laughable, it would probably be better to have no lights at all in there now. The bridge demon is a bit pathetic now, having half it's body just missing, and it looks like some of the wall faces have been removed as blank sections of wall are lit.
Some serious work needs doing on the finale too, it lacks any excitement (honestly, a face with a light inside?). Won't be too suprised if we see it closed for tic next year as hex is currently. I think to say it's beyond repair is a little far though. (Sadly) it's still one of the best dark rides in the country, and it's only a few scenes that need replacing/restoring. If you want to see a ride beyond repair, visit chessington...
