 * - Movies are displayed like so: Movie Name (Year)
 * - TV episodes are displayed like so: Episode Name (Show name, season x)

This is an example shortcode, created following the discussion in https://wordpress.org/support/topic/using-trackt-details-on-frontend/

The date handling is quite simple, it would probably need to be made more robust to accept different date formats. Right now it should accept any strtotime-compatible dates, e.g. "March 2, 2016".
