Well, I own BOTH, because even tho' I knew there was going to be another edition, I just HAD to have the original as soon at it came out. I AM kind of bummed that the additional scenes and new music weren't included, but I can accept these omissions since they, instead, thought the money and time would be better spent on the sequel. That's just fine, as far as I'm concerned. And the new DTS track is AMAZING! All the special features are great, but that track ALONE is worth buying the disc again (those of you who haven't experienced the sheer wonderment of DTS... I pity you...).
I DO have some complaints about how the DVD was produced, however - the fact that not all of the materials were presented in anamorphic is pretty annoying, since it involves me having to be a wee bit more "interactive" than I really want to be...
And why can't I just watch the damned deleted scenes by themselves? It's not that I don't WANT to watch the movie again, it just sucks that I have to interrupt the natural flow of the thing in order to just see them. Why not let us be able to to just look at them by themselves? Pretty poor planning if you ask me...
