Great api. One complaint.

Can y'all please include the movie rating in the /search/movie instead of making me have to make an additional call to /movie/{movie_id}/release_dates just to get the rating?

I can see why y'all do it that way since you're returning the rating in several different countries, but the US rating system is pretty mainstream, and not only used by the US. You could keep /movie/{movie_id}/release_dates how it is, and just include the US rating for /search/movie results.
