Two good aspects of this service for me are that there is a reasonably good selection of obscure films, and the only penalty for being absent minded is you don't get a replacement until you send the old one back.
To start you have to enter ten film choices into their system. I just thought of films at random.
Infernal Affairs
Delicatessen
Gangster Number 1
In the Mood for Love
The Killer
Rosencrantz and Guildenstern are Dead*
Southern Comfort*
X files Season 1*
Y Tu Mama Tambien
Scarface
* I've seen these before - the rest are new to me
It appears most of my choices are about intense relationships between violent men. Who knew? Anyway I entered those names on Wednesday afternoon, and this morning 'Scarface' arrived. We will see if the service continues to be so swift.
