My girlfriend took me to see this for my birthday present. It was pretty fantastic. When the T-Rex mom came out a number of little kids started to freak out and cry.
There actually weren't that many CG sequences in the original movie. Most of what you saw were puppets, big-ass robots and dudes running around in raptor suits.
Seriously.
Walking with Dinosaurs Live is fucking AWESOME, by the way. If you get the chance, you should definitely see it.
At the live production of Walking with Dinosaurs there is a narrating 'archeologist'(actor) who's probably mostly there to portray a sense of scale to the patrons in the higher level seats. Anyways, there was this kid sitting behind me who was just begging for blood. He was complaining to his dad that the raptors weren't attacking the narrator. "Why aren't they killing the man, daddy?".
