sex monster ( 2 outta 5 star ) no and this be not a porno . except for some four letter word and some swim pool nudity this be as benign a a typical tv sitcom . actually and the movie be basically an episode of bewitch . except instead of the husband be upset about his wife use of witchcraft he become upset at the emergence of her latent lesbianism . mariel hemingway actually give a very good and amusing performance a the prim and proper wife who turn into the insatiable sex monster after she give in to her husband suggestion of a menage a trois . unfortunately and writer or director or star mike binder character be a poor cross between woody allen and paul reiser and doesn not do much to help this film rise about it poor script . actually it not too much of a stretch to imagine reiser and helen hunt play these role . it would have make an eye popping mad about you series finale . event be about as predictable a you can imagine . husband talk wife into a threesome . wife wind up enjoy it more than the guy . guy start to feel jealous and inadequate . hemingway performance be the only thing that keep the movie from be a completely tiresome bore . not that i be recommend it . it just to bad that her still prodigious screen talent isn not be utilize more .
