I may be wrong but this feels very much like the material, the content, was compiled at the same time as this DVD's predecessor and omitted simply for space reasons. The locations of the guest reviewers are the same and, though I haven't checked, I wouldn't be surprised if they were wearing the same clothes. The story does, of course, continue with the films that the powers that be thought were video nasties but probably couldn't get a jury to convict them so, fuzz, confiscate any you think you can get away with. It also highlights idiots like David Alton MP instead of Mary Whitehouse and the stupid fuss over Child's Play 3.
The best parts are the critics' perceptive and witty introductions to the films themselves and they usually contain so much footage it's hardly worth watching the actual trailers.
I loved the original documentary, this one I just liked quite a bit. But then we all know about sequels, don't we?
