La Sed or Hijo de Hombre is an unkown, forgotten masterpiece. Epic, tragic, brilliantly crafted, I watched it three times and I could watch it again and again. If you love movies like Treasure of Sierra Madre or Sahara, you will love this one. One of the last scenes is tragically unforgetable: the hero is unable to drive a truck because his hands are burned. So a woman ties the wrists to the steering wheel with barb wire, the only thing the could find. Unfortunately it's unlike to find a copy. 10/10
