The Star Wars universe is not interesting enough for all the TV show and movies being made. George Lucas is not Tolkien and the world building was fine enough for the original trilogy, but it’s simply too boring for more content. Tolkiens work gets more interesting as you learn more about the details. Star Wars is the opposite. The more information you get the less interesting it is.
Also the Jedis are just cops/soldiers. They are not inherently good.
How much proof do you need. The Wikipedia page alone have tons of sources.
