I bought my 3D Monitor just for Creature, and you may be right but as we learned in above posts the 2D and 3D versions were a little different. If the box had stated 3D version included, I would be a little more secure as it is I'm wary. And thank goodness Warner does support classic 3D.
Because none of the other 3D releases were in a collection and Warner's may feel a 3D version in the collection would be a turn off to the casual consumer. But I hope I'm wrong.
