Though Mia Farrow came to prominence as costar of the TV series Peyton Place, much was made by network publicity flacks of Ms. Farrow's TV-movie debut in Goodbye Raggedy Ann. She plays an aspiring actress whose spectacular lack of good fortune in New York utterly destroys her will to go on. Mia is on the verge of suicide, when writer Hal Holbrook arrives on the scene and tries to talk her out of doing herself in. With Holbrook's guidance, Ms. Farrow realigns her notions of true success and gives life a second chance. Mia Farrow has always been a variable actress, but she's on target for most of Goodbye Raggedy Ann--whenever she isn't undermined by the corniness of Jack Sher's teleplay.
