TheTechLounge posted a review on the Roku Netflix Player

It's clear that the shortcomings are all Netflix-based, the greatest of all being selection. They don't have a lot of recent content, and they have a lot of content rated three stars and worse. Often with TV shows, they will have some but not all episodes of a season. But they're adding things constantly, and generally expanding as fast as they can afford to. By the time I thought I'd watched everything I thought was worth my time, I checked again and found an equal quantity of media gems. (Like Jesus Christ: Vampire Hunter. How can that possibly go wrong!) Of course, even that's not entirely up to Netflix, they have to prove to the developers and owners of the content that streaming is the way to go; there's a real "we're all pulling together" sense about this stuff. There's potential.
