Discover Calendar shows multiple premier dates for the same movie

Movies are showing up as releasing on many different days, often repeating over and over again on the calendar. This appears to be because they are showing up for every release late on TMDB, including pre-release, festivals and limited theatrical runs.

This makes finding new movies being released in theaters on a given day very tedious.

My suggestion to fix this:

By default only show the official nationwide release date. Optionally, make available the ability to see the other dates. This scenario seems much more likely what users would expect.
