Part 3 BD is definitely better than the DVD.
But I'm just saying that it didn't benefit from the darkening like the others (4, 5, and probably 6) did. When you take an already somewhat dark image and darken it more, you get some crushing, especially on scenes that don't need it.
4/5 always had more of a "brighter" look to them, at least on DVD format. In theaters, who knows. The darkening kinda gives them a bit more "polish" and makes them look more professional. Part 3 just didn't need as much as what was applied and it seemed overkill some of the time.
The audio is easily the worst offender. Part 3 has a great soundtrack (like Part 4), and the audio just seemed to lack the dynamic nature of the other movies in the set. Part 4's soundtrack is pretty vivid and robust in comparison.
And the logo has been replaced. Even Part 4's logo has been replaced, but I don't care much about it. Reason being, it was the standard "New Line" logo of the 80s and was probably used for all of their movies at the time. What the naysayers in this thread still don't understand, is that the logo for 2 and 3 were made specifically for the Elm Street movies. DVDmike is correct in his analogy as well. The black and red flashing logo blended in with the black and red quote that begun part 3; it was part of the experience. It was probably on the reel that theaters received during the release. I'm not screaming "rape" or anything, but I'm saying that this is more than a "petty" or "useless" complaint. It was pointless and would have been better left alone, just like the level of the darkening that was applied to 3. To compare the logo to the end credits is a useless analogy.
Don't get me wrong. The transfer for Part 3 is great, but it's the worst offender by a small margin. I recommend this set, but I don't think it should receive the "highest" recommendations from anyone. If all the movies were like the ANOES 1 transfer, then yes. It receives a strong recommendation from me so far. Keep in mind I'm viewing these movies on a 106" setup sitting about 7 feet away. There's nothing I don't see...

Also, I've basically confirmed that the 2/3 disc is the same as the US disc. I played the US disc previously, and just inserted the 2/3 UK disc to re-evaluate based on the last post, and it asked me if I wanted to "resume" playback.
I had to turn Part 5 off about an hour in. Couldn't take it. I'll see if I can hit up Part 6 later.
Also, to the person who said that the discs are confusing and blank, are you serious? Look at the outer edge. They tell you what films are on that disc.
