The blu ray interface doesn't promote anything other than what I have in my queue. I hadn't been on the website since I added hoc to my queue until i checked now. Of their top 10 for me I've seen 8. Which I guess means the recommendation engine knows my tastes, but it also means I haven't discovered anything new. The two other shows they listed I had heard of but I'm not interested in.
I did also watch an episode of ds9, and I may watch some more before my month is over, but I'm not going to pay $8/month to watch star trek.
