I used to work on recommendations for Google TV (Google search "what to watch") and I always wanted the team to implement a feature like this. One thing to be aware of since you're trying to monetize, don't be surprised if you see a cease and desist soon from the major studios and services for using their artwork. Netflix in particular is really strict here. Best of luck, I love the project!
Very inspiring that someone from Google likes my product!
Honestly, I'd be excited if I got a cease and desist lol
