Movies worth owning:

Fight club
Pi
Apocalypse Now
Fear & Loathing
Dr Strangelove
12 Monkeys
Good Will Hunting

Probably some Clint Eastwood too.

Funny how they're not romances or car-chase-explosion movies..

I'm big into plot. Generally I'm indifferent to acting; rarely (eg, in Kubrick films)
is photography noteworthy.

Also of course all the original Star Treks. None of the sequalae.
