Dear Academy, I'd like to nominate a baby for Best Baby? Thanks.
Ah... what can you say about Eraserhead that hasn't already been said? You will see things you cannot un-see. Not so much a horror movie or a drama, but rather a fever dream of indelible visuals and unsettling ambient noise swirling around a perpetually harried (and frizz-hairy) protagonist.
Lynch crafts a microcosm both vaguely familiar and lived-in, and yet cold, uncaring, and utterly alien, populated by characters as bizarre and off-putting as the world they inhabit.
Eraserhead doesn't try to make sense; it tries to make an impression. Love it, hate it, or grudgingly appreciate it (like I do) - you won't soon forget it.
