This kind of stuff gets really annoying. I've already got all three movies on DVD, but like any business, they add a few extras, repackage things and try to get you to buy the latest version. Haven't checked into this one, but often they simply repackage the original discs, maybe include some cute collectibles or put them in a special package, but it's the same thing we were buying five years ago.
With most purchases, I usually hold off for a year or so, waiting for the "Director's Cut" or whatever fancy term the studios want to call them, rather than buying the first release, which is usually just the basic movie version with a load of previews.
Sad part...I still haven't seen JP II+(How many are there???) all the way through. Just the first one.
I do remember when it and The Fugitive were "the main draw" in the burgeoning Home Theater scene. Both movies were on "constant loop" in the showrooms...
I already have all three. I'll be buying the 3D version too. I can't spend almost $50 just to get the trex. But I sure do love dinosaurs...nah can't do it.
