The fight between Yoda and Palp RUINED Yoda in my eyes.

Luke: "Is the dark side stronger?"

Yoda: emphatically "No!"

Oh really Yoda? In 900 years I guess your memory is fading... I take it you don't remember that fight where you lost to a much younger Sith Lord pretty handedly? And then fled like a dog that just pooped on the floor?

The fight needs to be similar to the Dooku fight in Ep 2: Yoda needs to be able to take on Sidious with no problem. The true fight shouldn't be between their "power levels" with the force - Yoda should dominate if so - it should be that Sidious fights dirty, endangering innocent lives or other would-be victims that Yoda needs to exert extra "Force power" to save.

Even better, innocent people die as Yoda is unable to save them all - but witnesses only see Yoda as Sidious flees the scene. Yoda then has to go into hiding due to the public's uproar against the Jedi and his own shame in not being able to save everyone...
