It's understandable to want a dark ride, but the problem with dark rides is creating a compelling story or at least creating an interesting concept for one which will withstand the test of time. Unless you're Disney or Universal, that's a tall order. That's why most theme parks don't have one, or if they do it's either not very good, or changes IPs and stories periodically.
Of non-Disney or Universal parks in the US, I can only think of one truly successful dark ride that has lasted for any length of time, and that's Monster Mansion at Six Flags Over Georgia. And even that has been tweaked and updated over time. The other problem is keeping a dark ride's effects and figures working consistently, which even the big parks have challenges with.
Let's see how the Sally Sesame Street ride holds up in the next year or two. I know the Justice League rides they built for Six Flags were impressive when they opened, but are not aging well, but then again Six Flags maintenance has a lot to be desired.
