Taxi Driver

I noticed a few instances that pointed to the idea of existentialism:

1. When Travis is on the phone and they show the loooooong empty hall
2. The sound of Travis drinking towards the very beginning of the movie, like all he focuses on is himself and how lonely he is and his life is
3. Everyone else is blurred out in one scene except for Travis
4. In his journal entries you can hear how sad and lonely he is, as if he is just existing in this world,
