People who like whatever the newest blockbuster POS is will not like Netflix instant so much, but for me, its fantastic.
Recently (in the last year) watched:
All of Knight Rider, Cosmos, Yes Minsiter, Around the World in 80 Days (Michael Palin version), The Story Teller (both series) Red Dwarf, and The Good Life.
A lot of Waiting for God, Inspector Gadget, All Creatures Great and Small, Faulty Towers, Ripping Yarns, Doctor Who, Mystery Science Theater 3000.
Also, Blues Brothers, Gentlemen Prefer Blondes, DC Cab, and a bunch of other movies.
