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. If anything, this will add to the already considerable wait for people not willing to pay for front upcharge fees.
