While I do enjoy this vekoma classic, this version of the Ninja is not comparable to Six Flags St. Louis' coaster of the same name.
As each year passes, the Ninja in Over Georgia continues to get rougher and rougher. The last time I went to the park, a lady was clearly wanting to get off the ride, but the train had rolled to far past the brakes and had to go through again. This made for one very unhappy lady, and for good reason.
The twisted concoction of metal makes for an interesting experience, but enjoyable probably wouldn't be the first word that comes to mind as you exit.
