Those entries considered non-canon include the series Dragon Ball GT in addition to the majority of the films. If you want to skip all the stuff that isn’t considered canon, i.e the series and films which don’t follow the events of the manga and were made without any input from creator Akira Toriyama, then there is an alternative order below. Dragon Ball Z: Battle of the Gods (movie).Dragon Ball Z: Wrath of the Dragon (movie).Dragon Ball Z: Broly’s Second Coming (movie).
This order does not take into account whether each series or film is considered canon or not – hence why some fans would say it isn’t the best way to watch – and as such it includes a lot of content.
While this method might be frowned upon by hardcore Dragon Ball fans, one way to watch the films is to go in chronological order in terms of the time scale of the story.
