The crotch shot was necessary *spoilers*
This just hit me. And I know the book goes into much more, but I just want to focus on the movie. I remember when it first came out, the IMDB board was rife with controversy showing Eli's emasculation. Many posters said it was unnecessary and just put in there for shock value.
But, NO. That scene had to be in there. Because that's one of the aspects the entire story revolves about. Let me prove it to you.
This story is so beautiful because it is about two lovers who are right for each other no matter who or what they are. Hence the double entendre of Let the Right One In. Let Me In was adapted for American audiences and I think while still a good movie, lost some of its meaning by putting the vampire plot more in the forefront. Even by shortening the title.
But the vampire stuff is kind of background to what is between these two lovers. It is still highly necessary because it is saying no matter what these two are, creature or human, boy or girl, they belong together.
I hope that someday our society will evolve enough to recognize love in it's purest state. I consider myself quite evolved because I opened the spiritual door 15 years ago and it has made me ahead of my time, for better or worse. But even I live by my identity as a hetero male. Maybe my soul mate out there is female and that's why, but what if--I will dare ask--what if I fall in love with another guy because we're perfect for each other? I already am a person androgynous in nature, being the sensitive caregiver guy and I'm into women like Caity Lotz (google her) who has an urban street vibe, knows martial arts, does Parkour, and talks a little bit like a dude. Yet she's still feminine enough to dress up and be sexy beautiful. I love dynamics in people so I get bored when I date just a girly-girl who is locked in that role.
So there you have it. The reasoning behind the crotch shot.
