Final Cut, but it didn't cut it...
I have all the various versions, except the international release, and honestly, I must be in the minority, because I believe the original release, with the voice over was superior to all the other versions. Sure, the sound quality is better, but the voice over provided a unique insight in Harrison Ford's character, and the added significantly to the storyline.
As far as the Final Cut, there was little evidence of scenes that had been added or deleted, and you would expect additonal footage to merit the hype.
I agree seeing it again on the big screen and hi quality sound was invigorating, and I LOVE the movie. But on the whole, what's the big deal?? The previous release on DVD was almost identical. It seems as if the studio was trying to make an extra buck off of those younger viewers who had never seen it before and the stalwarts who would go see it again, even if nothing additional was done. Fans love their movies, & would see it even if it wasn't digitally remastered.
