For those who said 'She Could Do MUCH Better'...
as in, Josie Davis being "hot" and that she could do better than Danny: with all due respect, your logic couldn't be more off (I'm guessing that perhaps most of you are on the young/er side??):
Women (and men for that matter, albeit perhaps for many different reasons), who sleep with children, generally do not do so, based on their looks, nor, is it really about sex: it's about power and seeking 'love' from those who are unlikely to reject you - at least at first. And I say "children," because while the age of consent might technically be 17 in most states, the age difference itself is reason enough to cause concern. Furthermore (and actually way more disturbing than a teenager having sex with juat any 40 yr old), is when there is a major power differential between even two consenting adults (eg doctor/patient, boss/employee). Doctors have had their licenses suspended or even revoked, if they engage in a sexual relationship with his/her patients. It's his/her responsibilty as the person in authority to not abuse that power, even if the patient, student, etc. were to do a striptease on his desk. So in a way, it's perhaps more egregious when this happens to a teenager - EVEN one who is already 18.
Women like “Molly” (Josie Davis’ character) seek out specific sexual partners for dozens of reasons other than his/her physical attractiveness. They need (and/or want) unconditional love (something we see in flashbacks that Molly never got from her abusive mother) and that’s easier to get with a child or teenager, ESP if you’re in a power position over him/her (so in this case, who knows why she targeted Danny – perhaps something about his ‘essence’ reminded her of her mother, whose love she had always sought). And I'm sure she probably was attracted to him, perse' (it's slightly better for a teacher to have sex with a 12th grader than a middle-schooler!!), but if it hadn't been Danny, it would've been another boy.
So my main point is that Molly was looking for that unconditional love she never received as child (not to mention that she seemed psychotic), so obviously, she’s incapable of having a healthy relationship with an age-appropiate man (though by Danny breaking up with her, we did see that developmentally, he was quite healthy and probably ahead of many of his other male peers). So when you say she can do “better” than Danny, she’s the one who can't have a healthy relationship with an age-appropriate man - so it's more like HE could do better, you know?? She's absolutely pathetic and SICK so while she might be able to pick up a handsome and successful man in a bar, she is incapable of having a relationship with such a man - that is, if he’s mentally healthy.
