said by darcilicious:Media streaming programs like Plex and XBMC display the ratings, genre, and synopsis; I think XBMC will even link to a trailer.
If you're looking for an automated way, I don't know that you would be satisfied with the results since "liking" something (e.g. a movie) or thinking something is "good" can be quite subjective.
XBMC looks nice getting it...
