Update Slot Types to Amazon Standard Names (i.e. AMAZON.Movie)

Try to avoid using custom slots and use Amazon's built in types    For movie names, use type "AMAZON.Movie".    You only need one intent "playMovie" with a slot for title (type = AMAZON.Movie) There is even a slot type for tv episode titles!! AMAZON.TVEpisode

The problem is that I believe these are currently only supported for US customers.

See #82 (which I believe this is a duplicate of).

As jingai said, only US Skills are supported at the moment. The built-in library is also only defined as a developer preview (though they haven't made any changes so far since it was made available Dec 7th 2016)

Makes sense, thanks all!
