"Eraserhead" is a movie you have to see once. "Once is the number that thou shalt see it. Not two. Not nonce....." Ummm, sorry, different movie; got carried away (say, no one mentioned "MPATHG" in the greatest war movie thread; fancy that...). Seriously, once. You should see it to say you've seen it. Provides a reference point, so to speak. A friend of mine who's a professional therapist says that it is the closest thing she's ever seen to the cinematic embodiment of a nightmare.

"But ... we're not even sure it is a baby...."

Enjoy!

Cheers,
