I don't understand Mystic River Falls at all and I'm so disappointed that the ride has been so problematic for them after all the expense and effort they put into it. It's such a beautiful attraction, but badly engineered all the way through. I've only been on it once myself since the lines have almost always been 2 hours long if it was even open, but I do remember it being strangely aggressive. I thought that was kind of awesome though. It's odd that so many people are getting injured on the drop specifically. The reviews are very mixed and there are a lot of head scratching comments about roughness and poor restraints. Rapids rides don't typically have these issues.
I'm still upset about it having such low capacity despite higher capacity being one of the main selling points of the ride.
I imagine at some point in the somewhat near future the ride will be reconfigured somehow. Maybe sooner than later if these lawsuits pile up. It would not be difficult to cut the tower/drop out of the layout and turn it into a more traditional river rapids ride.
