Is There Blood?

I recently viewed There Will Be Blood and well I know that I don't necessarily need to 'get it' but I didn't. Yes, I witnessed a man isolated and isolating by his compulsions. I noticed the distant aspect of the 'brotherhood,' it was the one venue that offered any hope to Daniel, but in the end they were both false brothers that he killed, was this the modern severing of faith and family?
Any thoughts out there on this movie? I had high hopes and I'm not sure what to make of it.
