Yes, I agree that she's made a series of lame choices. GRADUATE was a tacky, diluted (despie the lurid touches) version of a classic film, and Turner unfortunately put herself up against one of the iconic film perfrmances, Anne Bancroft's. Interesting about Mrs. Robinson: Bancroft had fewer scenes, fewer words, and was able to make far more of the woman's inner life (and pain). Even taking into account that film is more economical in terms of dialogue, etc. thatn the stage, it was a reminder that less often is more. Expanding the part for b'way, they turned her into a horny cartoon, and Turner couldn't do much with it.
Some of her interesting film work is in very understatated performances, like the basically supporting part in ACCIDENTAL TOURIST (the money scenes all belong to Geena Davis, even if her Oscar was "supporting."). I watched that again recently, and she's really lovely and effective with Hurt.
