I liked it
I thought Janeane Garofalo did a good job, and I liked the intelligent, offbeat humor: Janeane telling the dog she could cut him up and make him into Binky jerky, or asking Binky if he could say an anthropomorphized "I ruv ru."
And the pink Cadillac was a nice touch. I thought driving the pink Caddy would be more of a hardship than driving across country with a dog!
