This probably isn't for anyone under 21—except me. For the most part I found it quite funny and well done. The two stars are pleasantly low-key and quite good actors. At any rate—funny stuff for the right audience.
I love Tina Fey and 30 Rock and I expected to like this even more than I did. It definitely keeps you turning the pages, but fell a little flat for me. And it's not because I don't like chick flicks, actually, I do.
