I think this sums up a lonely soul. We all search for meaning in life, and we all want to save someone else - even the most misguided attempts count. The ending is great too, we all want recognition for our deeds but we live in dream worlds. Travis is a man who exists outside of society, he is not embarrassed by stupid things and is actually the most honest person in the film. I don’t know, I just think it gets eveything right and the casting is great.
