Even those with the eyes, ears and brain enough to realise this movie is crap still add the 'rider' (geddit) that Winona was the best thing and/or she was only coming off badly because her role was so badly written etc excuses excuses.
Fact is, she totally overplayed the girlie-girl giggly-skippy, I'm-a-wide-eyed-baby-me gushing simpering 13 year old and the numb klutz of a director appeared to just sit there and let her make an ass of herself and of the woman she's portraying.
So many of her gestures and expressions are so clumsily overdone as to be laughable. Watch especially the bit when Jerry gets his record first played by Phillips - there follows a kind of montage of scenes of reactions as they listen in also from the other characters such as family members. Towards the end of it, Winona/Myra is waiting by the phone - she speaks, hangs up and then goes into what is probably supposed to be a lighthearted rush across the room. Instead she she reels and thumps around, cartwheeling her arms like a dodgy propeller. She's supposed to move naturally, like an excited 13 year old, and she brings it in like she's method-acting a manic spaz.
Add to that her shreiking giggles and goofy faces - especially those scenes with her schoolfriends. I wonder if she was already hitting the percodans/oxycontin by then. Objectively watching her own efforts in the rushes should've driven her to the strong stuff when she realised that this movie was shaping up to be so bad that she was getting away with such a potential career-killing mess and especially that she was by no measn the worst offender in the *beep* stakes. Although in the bubblegum duets with Quaid she is a close runner-up.
