Welcome, Al Pacino!
The DVD set disappointed me in a way. I expected the audio and video to be vastly superior to the videotape 25th Anniversary Edition that I bought earlier. The DVD set was--but not by a lot. Of course, the 25th Anniversary videotape set was superbly executed (compared with the standard theatrical releases on tape). And, yes, MANY of the scenes in the DVD are annoyingly dark. But, the many extras are highly worthwhile, and go far beyond the interesting commentary at the beginning of the 25th anniversary tapes. And it's far, far easier to navigate to specific scenes on DVD than on tape.
In general, I have higher expectations of DVD audio/video quality than consistent experience bears out. I believe FFC and Scorsese, my favorite directors, could have done better jobs with the DVD versions of GF films, Bram Stoker's Dracula, Mean Streets (in mono), Goodfellas and Casino, respectively. The initial DVD release of Apocalypse Now was pretty mundane. However, the DVD of "Redux" is just spectacular!
