Why should you care about any particular title we recommend? What can we say about a new and unfamiliar title that will pique your interest? How do we convince you that a title is worth watching?
How about, instead of overpersonalizing everything, you say "we recommend X because you liked Y and people like you also like X."
I wish sites were more up-front about it. In many places, I get a recommendation and I wonder, "why on Earth did the site just suggest that?".
Steam does a little bit of what you suggest for games. When I browse their recommendation queue for me and I see a weird title, I can look down and see a little text that say something like "This game is suggested because it's new on Steam", or "because you've played similar games", or "because you've played games tagged XYZ", etc. It makes me feel that they don't pull the queue out of their collective ass.
