Please do not forget that, in film projection, some cropping is inherent to the projection process, assumed to be taking place by the filmmaker, and thus compensated for when filming. When transferring to home/digital media, then, some cropping is appropriate, in order to reproduce the image actually seen in theaters.

In my opinion, the 3D version of JP overdoes on the cropping department to produce a very bad framing from the original one. And Jurassic Park being an already tight-framed movie, doesn't help either!
