It's a good, guilty pleasure. The satire is mostly warmed over, but the occasional physical punch line, the general look of the show, and, mostly importantly, the sympathetic performances of the actresses themselves make it work for me. Not the greatest show ever, but one of the better ones on T.V.
Contrast that with the utterly derivative 'Boston Legal', an uninspired cross between 'Ally' and 'The Practice'. David E. Kelly has truly gone off the deep end and has reached the point he's been heading towards for the last decade; creating a show with not a single sympathetic or even sensible character with more than three lines. At least if the 'Housewives' are shown being put on in a dated way, their situation has some foundation in reality, as oppossed to the completly sexist, arbitrarily victimhook foisted on the female 'characters' in 'Legal'. No thanks, I'll stick to 'Nip/Tuck'.
