Guys, you're complaining about the queue themeing, but what theming would a forest have apart from an abandoned van, leaves and severed branches? It'd be nice if they had more trees, but they take TIME to grow. Give it 2/3/4 years, and it'll be a hell of a lot better!
Lots of abandoned broken buildings/ruins. Lots of rusty old machineary (fits with the restoration theme). Maybe a wooden shed/hut. Really all you need to do is look at films which feature creepy forests and take inspiration from that. I'm sure a good Production Designer (read set designer/scenic artist) would come up with many more and better ideas. Most of these things can be obtained for free or very cheap. Hell, give me some woodland and access to a scrap/reclaimed yard and I'll build you a better Dark Forest than alton towers did.
And what about this "ancient buriel ground" the ride was apparently built on as part of the back story (which now of course, they claim there is no back story :? ). I think the asda halloween gravestones at the switch track dont quite cut it, do you?
