I've been thinking about this lately and I believe Yoda is overrated. Yes, he's 800 years old and a Jedi Grandmaster but for someone with all of that skill and knowledge, he didn't accomplish much. He couldn't see the Dark Side when it mattered most He couldn't beat Sidious. He ran away(crawled away like a rat) when the stakes were highest. His own apprentice went to the Dark Side. He didn't prepare Luke well enough to defeat the Emperor in a straight up battle either. Qui Gon communed from the dead and he had no idea about that skill until Qui Gonn contacted him. I understand that the story needed to be told and that characters would be flawed, but Yoda turned out to be pretty pathetic.
