We had Delicatessen out on loan from Blockbuster, oh, fifteen or so years ago, but the tape was buggered, and we never got around to re-renting it. A friend WINOLJ loaned it to me recently when this particular fact arose.
It's... weird. As if Brazil was done by a Frenchman. A mad Frenchman. Visually, it's very impressive, with damp, foggy, decaying architecture shot through with a sick yellow tint (imagine Gormengast at night, in sodium lighting). It's set in some post-apocalyptic world, in a boarding house packed with weird folks who are all mostly unpleasant. And a nice, new, unsuspecting gentleman comes to stay...
I loved the strange woman with her Heath Robinson contraptions, but mostly it was a parade of bizarre grotesques, and I'm left with a lasting sensation of, "well, that was weird. And Yellow. And foggy. Next?"
I much preferred Amelie.
