Decent, but not excellent. They have a lot of films that conventional video rental do not carry, but they do not have really rare stuff. For example, I unsuccessfully tried to rent Dodeska Den (Akiro Kurosawa) which is available on DVD. Same for Nasty Girl by Michael Verhoeven. But they carry some good stuff too, including Death in Venice, Triumph of the Will, or Dss Experiment.
