Depending on the version, it has essentially the same amount as sugar as coke per oz.  

Per 8 oz:

100% juice: 23g
Cran-rasberry: 27g
Coke: 26g

..I guess it has vitamin c and potassium? It's basically a soft drink though.

Most fruit juices are that way. You take out almost all of the good fiber and nutrients from a fruit, and leave behind the sugar. In the case of cranberry juice they add extra, but other juices are just as bad. Orange juice has 26 g/sugar per cup, and apple has 28.
