Well, from the books I've read so far I found only the Darth Bane trilogy and now the Plagueis which stands out and shows some exciting intelligence behind the Dark Side. Others seemed to be one dimensional and they couldn't really elevate to a level beyond simple arrogancy to even remembering them so my memories are vague here and there
On the other hand the whole Lucas universe is a complete mess if we want to dig deeper than the surface. As it was mentioned before, the mind trick is pretty much one point where the concept is bleeding and force push is the other for jedis (however in the D20 RPG it was somewhat regulated in use and wouldn't cause any interference using it on non-living creatures like droids. But everywhere else it's being used with a great smile.)
All seem to go back to the good and bad opposition.
It's my very personal opinion but if the jedi order also has the concept in mind about good and bad and it's just somehow different to the others' approach, then they are not really legitim to "guard the galaxy"
In my theoretical jedi order there's no good and bad but things as they are. Guarding means intervention and needs a concept to back it up. The Dark Side is also just a label to another concept which is different and - how funny - the whole "light" and "dark" names are established by those who claim to be the light
So I agree to move away a bit from the core of the movie-line when it comes to research and contemplation. Certainly and interesting discussion. Can't wait for the jedi academy to be set up too
Plagueis is a stand-alone classic for any Star Wars fanatic. It is the one novel in the canon(or non-canon or legends or whatever) that draws me back time after time & never disappoints.
It can chill you to the bone with its emotional depth in a way no other SW book does.
Not saying I have read them all (but I have read a great deal of em lol)
The Lucas universe & beyond is a mess! But its our mess & I love it.
Edit: Ahh, I seem to have commented on something from about a year ago. Apologies. My very late comment stands though.
