One of the best older movies I've EVER seen. It's not only a thriller, but rather also a looking glass to show us what we may well become in the future. A classic film (not to be confused with the 2002 shitty remake).
"And out there in the great big concrete jungle I wonder how many others there are like me. Poor bedeviled guys on fire with thirst..such comical figures to the rest of the world as they stagger blindly towards another binge, another bender, another spree."
