Star Wars: The Clone Wars

I was showing my GF star wars on Saturday and we were watching the clone wars.....it was that time. I had showed her the original trilogy already so i had to show the new one. we watched phantom menace a while back. so we were watching the clone wars. That movie is easily the worst of the 6. I do like lots of parts about that movie however. I like a lot of the locales, I like the ObiWan plot and I like the fighting.
So when Obiwan is captured by Dooku, before Anakin and Padme get to the planet, Dooku tells Obi Wan what is going on: that there is a sith lord in charge of the galactic senate who has brainwashed so many senators into following him. He says this dark lord will end up ruling the republic and that he invites Obi Wan to join him to stop the Dark Lord. He says the trade federation was betrayed by this dark lord 10 years ago, which is when the clones were commissioned to be built, by the jedi.....but i was reading that Dooku split off from the Jedi and joined the Trade Federation. he is literally telling Obi Wan what is about to happen to the Jedi, and Obi Wan spits in his face. We know that Sidious is the bad guy. its pretty dang obvious. So, is this the moment of greatest tragedy? Dooku is trying to stop Sidious and SAVE the republic and NONE of the Jedi listen. Not Yoda, Obiwan, Mace Windu. It's in front of their faces if they open their eyes to see it. The Jedi are their own tools of destruction....I had never even thought about that before and for some reason....it made me enjoy the movie that much more
