What gets me is it's like they ran out of ideas for what jedi could do, especially light side jedi. In the OT they can lift/manipulate things telekinetically, use the jedi mind trick (which is useless against other jedi, apparently), jump high (Luke in the carbonite room), and that's about it. Dark side guys can do that stuff, (force choke is basically telekinesis with an evil purpose) plus shoot lightning bolts. In the prequels they added force speed, but only used it in ep 1 iirc. Oh and I guess Yoda absorbed Dooku's lightning in ep 2. Not sure if that counts as a new ability, since apparently he forgot how when he came up against Palp in ep 3.
Granted, they apparently have other abilities, like limited prescience, but these are explored only a little ("it's why he appears to have such quick reflexes" during ep 1, or Palp "foreseeing" everything happening in RoTJ other than his own death).
There must be some more powers they could give Jedi without being too "wizardly" about it. Even the Star Wars video games are kind of lacking when it comes to new abilities that jedi might have, and they have way more leeway to do new stuff. Most of the force abilities in the games I've played involve buffs of some sort, or new lightsaber styles, or some variation on abilities we've already seen. None of which lend themselves well to a movie environment where we need to SEE what's going on.
So, since they had no ideas for a master light side jedi like Yoda could do other than telekinesis, they were forced (heh) to go to lightsaber combat for him, which didn't come out right at all.
Personally, I'd have had him using a lightsaber with the force, while he just stood there directing it with a condescending look on his face. But if that doesn't work for whatever reason, just have him be WAY more powerful than other jedi with telekinesis, like he could have entombed Dooku with rock from the walls in like a second, leaving him to try to escape by burning his way out maybe, I don't know. Or maybe he could create illusions of himself for Dooku to go after, anything but flipping around like he did, jeez.
