Am a Netflix user, but really don't like the interface. Old one OR the new one. Honestly, while the Blockbuster service wasn't as great, the actual interface was much better. Also had sortable categories that made sense for what I was looking for: Releasing this week, next week, as well as In Theaters, so I could add things to my queue when I was thinking about them and have them show up when they came out.
The netflix system is an irritating POS. Honestly, i usually log into my blockbuster account (inactive), run my searches, and then type the names into Netflix manually. Not exactly ideal...
