You mean that knackered, noisy and now ancient ride with no theme?
No thanks. :|
I think the original Haunted House would be top of my list.
Old and knackered? No theme?
Old and knackered basically is Forbidden Valley's theme mate. ;)
And anyway, have you never heard of renovation or re theming?
No it's not it just hasn't been looked after very well. What has "renovation" or "retheme" got to do with anything the Forbidden Valley theme was added when Nemesis was build Thunderlooper was left untouched.
It had a very basic station and platform and didn't fit in to the new area at all. Not the reason it was removed but it is clear they weren't to bothered about either Thunderlooper or the New Beast being there because they didn't even attempt to retheme them.
