I also think the Jedi die to easily. Well maybe I don't mind that Palps could dispatch them so quickly, but it didn't look good on screen. One Idea I have had, was to remove the Sith Lightning from the Dooku Scenes so that we haven't seen any Sith Lightning in the series yet. Then when Palpatine leaps from his chair, I would add swirling Sith Lightening that attacks the Jedi and holds them frozen while he cuts them down, with only Mace being able to hold it off.
