Bad Writing a-Go-Go

Here's part of the intro to Denver Post movie critic Michael Booth's review of Knocked Up:

Writer and director Judd Apatow makes movies that advertise red-hot pepper flakes on the outside, and deliver talcum powder. Crass and caustic jokes rub the tongue raw, only to be followed by a big drippy orange Creamsicle of self-improvement, hope and monogamy.

Wha? How exactly is one able to compare red-hot pepper flakes and talcum powder? Is it the differing colors? Does Booth think people are applying red-hot pepper flakes topically?

And does he really think Judd Apatow wants to rub our tongues raw? If my tongue was ever rubbed raw, I'm sure I'd need more than a Creamsicle.
