I hate to be the one to bring this up and I genuinely hope that someone can offer a more positive view, but I actually found Lynch's representation of women to be fairly offensive in Lost Highway. Though this was the first time that I have ever seen this movie and there is a good possibility that I'm leaving out details or forgetting some plot points, it seems as to me that the women in the movie were almost completely used as sexual objects. The only two women in the movie I can think of were Patricia Arquette's characters and Pete's girlfriend and both really only seemed to be preoccupied with the men in their lives and both were used in sex scenes that pretty thoroughly objectified them.
At the end of the movie, I really couldn’t tell you what the point of Renee’s character was. As far as I can remember, I think she had sex with literally every other character in the movie with almost no explanation for her motives. If it is true that she was having an affair with Mr. Eddy, why would she do that? He was a contemptible old man and Lynch seemed to make it clear that Renee didn’t owe him anything, it was only Alice that did. Also, why did Alice begin having sex with Pete? I don’t think she genuinely cared about him, as seen through one of her last lines when she tells him “You’ll never have me.” But I also don’t think she was just using him to get away either, because she didn’t really need Pete to get the money. She was already in Andy’s house. Why didn’t she just take his money and run away? I think I would have less of a problem with the gratuitous sex scenes if Renee’s motivations were explained at all. Instead, it just seems like Lynch just put her in the movie as an excuse for really long sex scenes. I hate to sound like a prude, but it just seemed extremely unnecessary. My discomfort might also stem from the fact that while watching it in the MRC, someone asked me if I was watching a porno.
