Best Classic Movies With No Love Interest?

Either no love interest, or a very limited one..

It seems almost every film has it. I guess after seeing thousands of love stories, I want something different.. getting bored, running out of movie ideas. Sometimes it's a good thing, but usually it's an easy way to get the audience. Whether it teases the audience, excites them sexually, or if people live vicariously through them or their own personal fantasies, carnal or platonic, or using a character or a scene as a metaphor for your own life.

I remember Ebert criticizing "There Will Be Blood" for not having a love interest. It did - between H.G. and Mary, but it's not milked. I think that's the best one without it being the center of everything. It's more subtle and pure, rather than devious and exhausting.

If you have a film you'd recommend, here ya go, I'm constantly trying new kinds of films, different director. I can only imagine a great film with no love interest being pretty great if it can stand on it's own without using sex or love or both to fall back o to kill time. It's like a lot of the bands I love - they are still my favorites, but I find myself not wanting to listen to them, and sticking with songs that are either brand new, or songs I haven't heard in a really long time.
