Well, according to Safari Mike they very well might be. Primeval Whirl has long been the target of Disney World's critics, but according to the new review posted today it simply does not deserve all the negativity.
For those who have never been on Primeval Whirl, Safari Mike gives you a full rundown of what to expect from this "Wild Mouse" style coaster in his brand new full review. While it is not the best attraction in DAK, it is by no means something to be skipped without at least giving it a shot.
