I...might see it, only because Jurassic Park begs to be seen in a proper theater, particularly for the sound. I had a thought that made me feel old, though. The timing is great because there's a whole lot of people who really never saw this movie or were very young when it came out, as well as the group how saw it long enough ago that they'd fork over for the nostalgia (my camp). It's bloody brilliant from a financial perspective. Millions at the box office for a theatrical release, a second time.
The 3D itself is not at all a factor in my decision, and does nothing to enhance my movie going experience. The glasses make everything darker, messing with the contrast and colors. The 3D doesn't impress me at the theater, I remember rides at theme parks that actually made it feel like things were right in front of your face, so I don't know what's up there. All I get out of it is a weird added depth perception.
