Nobody says you have to make a completely useless post, either, Joezzy. Araknis brings up a valid point that it's not the whole story (it does not advertise itself as "The Whole Theatrical Story", A.M. Review, so don't falsely claim that as the reason), but your post is absolutely pointless. Sure, Araknis doesn't have to buy it, but Dreamworks doesn't have to falsely advertise that this is the "Whole Story" either, especially when clearly it isn't.
well the christmas special IS on there. i doubt they'd have have that 3D ride. though that would be cool but if Back to the Future and Terminator dont add their 3D mini-movies, dont see them doing it either. as for the halloween special, that is a little odd. i recall last year that the christmas special was announced on dvd before it even aired on television so they obviously would have had the time to add it to the box set.
but you're buying this for the movies, hence why everything else is called "extra" or "bonus" material. but i'm sure there will be another collection within the next year or two that will inlcude the halloween special and whatever else may be around by then.
anyone who buys movies knows that no release is EVER the complete collection. there will always be a chance that a newer version comes with even more stuff. hell look at the Alien movies, they are re-releasing the quadrilogy with new extras but there's the recent announcement of two prequels so it still wont be complete. (you can throw in the AVP movies if you want as well) thats just the reality of home entertainment.
