I like the Ripley novels too and I agree with you that reading her as a "gay icon" is detrimental. I was commenting on her personality and eccentricities and I would avoid reading those into her books.
> Mostly those movies miss the main point of the character: he's egocentric, manipulative and ultimately sleeps like a baby without any guilt whatsoever once he's done murdering whoever stops him from that. All the tension in the books is about avoiding getting caught, which usually leads to additional victims. Not very compatible with the average Hollywood movie of course but it makes for an interesting anti hero.
I read Tom as a rebuttal to Crime and Punishment.
As far as the adaptations, Ripley's Game is my favorite. Malkovich gets so many good lines. Purple Noon is pretty good too (Alain Delon is great) though the ending is weak.
