I had the "Banned..." set, but returned it, because so many of the discs were still cut.
However, having said that, the final disc with the two documentaries on it, is exceptionally good, and it may be worth your while buying the set just for this, and the uncut "Zombie Flesh Eaters" DVD, which also has some excellent extras on it.
But, the vast majority of other titles in the set, are still cut. Only "Zombie...", "Driller Killer" and "Evil Dead" are genuinely uncut. For £14-99 it may be worth paying for the set.
Umm, it's called the "Box Of The Banned" because the films were all banned at one time or another, during the early 1980's in the UK! Just because the films aren't all uncut on this DVD set, doesn't mean that they weren't banned at one time or another!
