When I first heard about this coming out I quetioned whether it was worth buying, on the basis that I already had a "making of" documentary from the Elm Street box set I bought a few years back. All I can say is, having had to take two nights to get through this one (the main documentary is 4 hours long), I'm glad that I took the plunge. Fantastically detailed (but not in an overly-dry way) this documentary really does tell the story behind the making of each of the films (and includes a brief overview of the pretty awful TV series). Personally, I think the best thing about this, as compared to your standard "making of" is that it benefits from hindsight. The contributors all feel free to note what they think did or didn't work and are pretty unflinchingly honest in this regard. I'd also add that, although I'd only expect fans of the Elm Street series to buy this, it is also an interesting insight into the world of the independent production house (in this case, New Line). Any downsides? Not really. Although it is a shame that some of the more famous stars (most notably, Johnny Depp and Patricia Arquette) weren't part of the interviews, but I don't think it lacks for anything in their absence.
