'Grey's Anatomy,' 'Private Practice' are adrift

The once-formidable show struggles with implausible plots and diminishing characters. > T.R. Knight, beware. Semi-public rumblings about one's desire to be freed from under the firm press of "Grey's Anatomy" creator Shonda Rhimes' thumb have a way of not ending so well. Witness the case of Katherine Heigl, who moped about the lack of quality material the show was providing her and was subsequently punished with scenes requiring her character, Izzie Stevens, to have loud orgasms while copulating with the oddly manipulative ghost of her late love, Denny Duquette (Jeffrey Dean Morgan).
