They're doing one count better than Chessington then, which still hasnt got a new coaster after 15 years! I may discover whether it's abysmal or not but I feel more inclined to go visit parks like that than most UK parks at the moment. All down to value for money.
It was a bumper year for the park, but then why have all their other IP attempts at Thorpe since been such big flops? The entire park was in a different situation. They're now feeling the pinch after years of too much focus on short fads instead of long term redevelopment and improvement.
On the subject of IPs. Merlin have just tried to suggest in their interim results that its Legoland performances have been disappointing because the Lego Movie 2 didnt bring in the extra guests expected. But they'll still build more and more Lego Movie attractions anyway, becoming even more reliant on the performance of other media rather than build the quality of their own parks. IP popularity can be used to boost parks in the short term but overusing it like Merlin do will just come back to bite you.
