Hi and welcome Skywalker80 !!
First of all, I got to admit (again) that I liked the voice-over in the original '82 cuts and after seeing the deleted & alternate Scenes on disc 4 I wish we could get to see more of the voice-over and the alternate scenes but the Final Cut is the one I prefer now, with it's splendor (image quality is top notch) and with the errors corrected..
The Final Cut is the one to choose if you ask me !!!
Extras is always a nice treat when it comes to DVD's but whom could have guessed what we got to learn from the extras in the new 5-disc editions of Blade Runner. [spoiler]I mean, who could have guessed that Deckard had an ex-wife.. or maybe that was just implanted memories ??[/spoiler]
