Cool story, Ken.
Over the weekend, showed my 6 year old his first Star Trek movie. Went with IV, figuring it'd not be too violent/scary - KHAAAN! will have to come later. Also, I didn't want to subject him to the boredom of, say, I or V. I also hoped he'd find the whales interesting.
Fail. Overall, he found it boring - he's too used to the faster pacing of the PIXAR and Dreamworks animated films. Also, I remembered that the movie had a few "colorful metaphors", but I didn't remember how many.
He did laugh when the harpoon hit the Klingon ship. And, he's curious to see a Next Generation movie, since he has a Geordi La Forge action figure. Hmm.
