In Star Wars lore, it's safe to say not everyone was a fan of Anakin Skywalker. While Qui-Gon Jinn and Obi-Wan Kenobi felt he could get trained as a Padawan after coming to Coruscant from Tatooine, many Jedi Masters felt Anakin was too old. He was a risk in their eyes because they preferred younglings, not a kid who was emotionally unstable after a hard upbringing. That led to Anakin giving the Jedi Council a lot of lip as he grew older, especially because he had the rebellious spirit of the deceased Qui-Gon in him.
