Almost entirely positive reviews, from what I've seen so far.
I should also add that Knott's has added Iron Ride to its list of rides using Fast Lane, the front-of-the-line upcharge fee available for a limited number of visitors per day. https://www.knotts.com/plan-a-visit/...-pass?mobile=0 If anything, this will add to the already considerable wait for people not willing to pay for front upcharge fees.
