Chrysler's Dr. Z campaign puts me to sleep, which is hardly the ideal car-buying state. These spots are everywhere and, yet, they are so remarkably underwhelming. The copy isn't clever, funny or memorable. And, while I'm sure Dr. Z. is a nice guy, he comes across as interesting as wet cardboard on screen. He should be replaced by a talking U-joint that wears a funny hat, or maybe Billy the Chrysler Monkey.
