Masterpiece.
Amazing performance by Peter Lorre and divine Direction by Fritz Lang in a very agonizing story.
I could say so many things about this film, but I think it's important to just point out the ending: we failed and continue to fail with our children; evil lurks amidst the normality of this world, amidst everything that is common, and the kids are the purest and most innocent thing, which is precisely what this evil seeks in all its forms.
Honestly, I still have a lot to think about regarding this film; perhaps I'll add more thoughts at another time.
