^If it's sunk that much in just a day, then it could rise just as much by tomorrow. It takes time for a consensus to emerge.
Note also that the 58% rating for "all critics" is given a "rotten" symbol while the 60% rating for "top critics" -- which is statistically indistinguishable from the former -- gets a "fresh" symbol. Clearly the dividing line between what they label good and bad is rather arbitrary, and the icons are a gross oversimplification. (I read at least one "rotten"-labeled review that was actually largely positive. A binary system like RT's is not good at dealing with nuance and ambivalence.)
