If that's the point, there's no doubt people misinterpret films all the time. And align themselves with characters for the wrong reasons. There are lots of reasons this can potentially happen and many might do the same thing about Harold and Maude. But I can barely speak for myself, so I can't fret too much over how other people take things. I only try and articulate how I've intererpreted something, and in this case, I'm just trying to talk about how I don't have any issues with overlooking the bad behaviour of characters in some films.
But yes, absolutely. I wouldn't watch The Fast and the Furious and complain that car theft is wrong, damn it, wrong. Of course, I wouldn't watch it at all, but if I did, I wouldn't object to it on those grounds.
