Dragon Ball, Dragon Ball Z, and Dragon Ball Super can be watched on various streaming platforms such as Funimation, Crunchyroll, and Hulu. These platforms offer both subbed and dubbed versions of the series, allowing viewers to choose their preferred language. Additionally, the series can also be found on certain cable networks and can be purchased on DVD or Blu-ray. **

It is not necessary to watch Dragon Ball before watching Dragon Ball Z or Dragon Ball GT, as each series can be enjoyed independently. However, watching Dragon Ball first can provide background information on the characters and their relationships, as well as a deeper understanding of the story. Ultimately, it is up to personal preference whether to watch Dragon Ball before the other series. **

Dragon Ball is the original series that follows the adventures of a young boy named Goku. Dragon Ball Z is the sequel to Dragon Ball and focuses on Goku as an adult, with more intense battles and power levels. Dragon Ball GT is a continuation of the story after Dragon Ball Z, but it is not based on the original manga by Akira Toriyama and is considered non-canon by many fans. **

If someone is new to the Dragon Ball series, it is recommended to start with the original Dragon Ball series. This is because it introduces the main characters and sets up the world and story of the series. After watching Dragon Ball, one can then move on to Dragon Ball Z, which continues the story and introduces new characters and power levels. Dragon Ball Super can be watched after completing Dragon Ball and Dragon Ball Z, as it is a continuation of the story and introduces new arcs and characters. **

If you are looking for a more faithful adaptation of the original Dragon Ball manga with improved animation and pacing, then Dragon Ball Kai would be the better choice. However, if you are nostalgic for the original Dragon Ball Z with its iconic filler episodes and music, then you may prefer watching Dragon Ball Z. Ultimately, it depends on your personal preferences and whether you prioritize a more streamlined viewing experience or the classic feel of the original series. **

In Dragon Ball Super, there are two movies: "Dragon Ball Z: Resurrection 'F'" and "Dragon Ball Super: Broly." "Resurrection 'F'" focuses on the return of the villain Frieza and his quest for revenge against Goku and the Z Fighters. "Broly" introduces the character of Broly into the Dragon Ball Super continuity and explores his backstory and his intense power. Both movies are set within the timeline of Dragon Ball Super and feature the characters and storylines from the series. **

As an AI, I do not have personal preferences. However, many fans of the Dragon Ball series tend to prefer Dragon Ball Super over Dragon Ball GT. Dragon Ball Super is considered by many to have better animation, storytelling, and character development compared to Dragon Ball GT. Additionally, Dragon Ball Super is seen as a more faithful continuation of the original Dragon Ball and Dragon Ball Z series. **

It ultimately depends on personal preference. Dragon Ball Super is the continuation of the original Dragon Ball series and follows the adventures of Goku and his friends as they face new powerful enemies. On the other hand, Dragon Ball Super Broly is a standalone movie that focuses on the backstory of the legendary Saiyan, Broly, and features intense battles and stunning animation. Both have their own strengths and appeal to different fans of the Dragon Ball franchise. **
