I wasn't implying classic dark rides are only for kids, but more stating that the Land of Dooz and subsequent Smurf Mountain overlay seemed to be more geared towards that audience over older crowds based on various descriptions I've seen (including Dale Brumfield's), even though practically anyone could ride.
In current times, I don't think they'd want to pigeonhole a dark ride as being geared for younger guests, nor does another shooter ride make much sense. CF seems to not be interested in another coaster/dark ride hybrid after building Wonder Mountain's Guardian... And it seems unlikely the park will get the budget needed to build a new dark ride at DK levels of immersion or better.
Therefore, I'd be curious as to what kind of dark ride they would place in JX (or the park in general given a somewhat small one could go in the old Action Theater).
However, none of that is to say they won't or that they shouldn't - I think a dark ride would be a good addition in general, especially for winter operations.
