Yeah, the second half of the film doesn't make a whole lot more sense than the first.

At least I got to draw God. (Well, "God" anyway.) That was fun. Now I know why there's all that Old Testament stuff about an angry God - He's so much more fun to draw that way.

The forward observation room on the Enterprise-A is pretty cool though. I like to imagine that ship's wheel is functional, and Sulu could control the helm from there.
