If this new scare maze is in Sub Terra's area, it can surely mean only one thing. The Dungeon will indeed be where Charlie was.
Such a disappointing and unimaginative use of CCL. As someone who is much closer to in distance and has much more of a history visiting Drayton, I loved looking at pictures of Space Leisure's work on Talbot street in the 80s and seeing how the area evolved, and sadly declined leading up to now. The idea of Towers not just being a theme park full of coasters, but also full of museums, shows and alternative attractions relevant to Staffordshire history really draws me in and makes me wish that I'd have been alive to see these places back then.
Instead, as with all the other 'redeveloped areas' Merlin have done at Alton Towers, CCL was a cheap repaint of the Street with a few dots of tiny theming here and there. No major investments at all, bar the cinema which isn't even open now.
And here was the prize opportunity to completely re do the area and add a giant new attraction, ideally a flume or dark ride and give the area a Gothic, Victorian or Tudor theme... and this is what they do...
I'm not being close minded, and I'm not saying that I'm 100% certain the Dungeon will be dreadful (only 99%), but I truly am expecting a poor clone. At best it will have some relevance to Alton Towers (they'll find a local witchcraft story for the witch bit, and a local area for the plague bit and none of the gimicky mirror mazes and drop towers) at worst it will just be a carbon copy of other dungeons with even less relevance to history.
The simple fact is, it's theme is very loose, and involves a lot of identical branding, and it contrasts heavily with CCL. It's dark, and dismal, and doesn't require much in the way of appearance. If TLC are a 3 year project, and this is their last piece of work, then I think this area with a lot of interesting history integral to the identity of the park will not be around for much longer.
