Oh damn! I did not expect that at all tbh, but it sounds great.
At 537m it's perhaps on the shorter side for a coaster, given it's got multiple launches too. The way it's described, I'm setting my expectation to something more like a dark ride with coaster sections. A Movie Park Germany take on Gringotts if you will, which has the potential to be fantastic imo.
I honestly have a soft spot for Movie Park, and this is a great investment in general. It's been a great few years for the park, and with the quality of their other recent investments, I think this will be another sleeper hit of an attraction!
