Actually, you're completely wrong on one very important factor of your review. There are no "updated effects". This box set is exactly the opposite of that.....it contains the original, theatrical, non-updated versions of each movie. The prints of the films themselves have been digitally restored (removing dust, hairs, dirt and a digital noise reduction), but the effects are as they were upon release.
It is the previous release.....the 2 disc 'director's edition' versions of the movies (now out of print on DVD) that contained updated effects of certain scenes.
