How to watch Pokemon?

Pokemon anime includes over 20 seasons, and over 20 movies, many of which have a number of releases. Including separate releases, and collection releases. It may not be easy to understand what is what, and what to get. To make it easier I did made list on Pokemon anime releases from Amazon (affiliate links). Arranged by seasons, and with picking collection editions when possible (both type for movies).
