I also use the Streaming only part of the service and I find very useful.
Most of the Star Trek series are on there now. You've got The old and new Sherlock Holmes TV shows on there. Top Gear for the automotive fan, MythBusters for those who like Experiments and explosions. They've got both Hollywood, and foreign, some documentaries that I find quite interesting.
You need to have a good and fast (not fastest) Internet Connection though. This won't really work for you if you don't have that.
