On a recent visit to the states I got to try out Netflix, and on being told you could watch any film you wanted was very impressed.
Turned out there are only certain categories of film (i.e. the ones that would be on daytime tv..) you can watch on "freeplay" and anything good you have to wait for a DVD in the post.
No wonder its cheap. Was still better than the adverts every 8 mins while watching Rambo on a cable channel though.
