Be advised - it isn't like the book. I would recommend reading the book as well.
TV Movie stuff:
I liked the fact that they get the basic sound of the music, but I missed the opening voice-over. If this becomes a series they might reinstate the opening dialog.
I also enjoyed the part when Mike drops a chip on the floor and KITT displays an image of Chief Iron Eyes Cody from the old anti-littering tv commercial from 1971. Here's a link to the ad on YouTube - Crying Indian
I didn't like the gratuitous sex scenes. The two girls in bed with Mike and the lesbian scene with the FBI agent added absolutely nothing to the story. Afterall, we watch Knight Rider to see a cool car and driver beat the bad guys.
If it does become a series I will probably watch a few episodes.
