Looking at the photos it does seem to be good theming, I especially like the use of using the phone box that's used in the TV series! This being said though I'm still a bit undecided on the idea of using IAC. The idea seems good but I can't see them executing it properly without coming across a lot of problems. Yes it IS a popular show, and it could be good, but putting it in Thorpe Park just for the sake of something new for 2015? Nah. Like it's been said higher up, would be suited better to Chessington. I don't know what I expected with those clues but it definitely wasn't that, so they've surprised me to say the least...
(Unless the famous Tucker is the prize for winning all the stars. Then I'm totally down with that.)
