I thought it was great! The books really helped to get it. Sam Rockwell did a great job as Zaphod (who's voice oddly resembled George W. Bush.). Alan Rickman did a great job as Marvin. I didn't really care much for Trillian. She was pretty hot, but that's about it. I was suprised at Mos Def, he did good though he wasn't my first choice for Ford. And the guy who played Arthur was good too. The end.
