Well, here goes the ones I like
Kreia:I think that she is absolutely a very strong character.She had really powerful lines,from beginning to end,and I like the way she's bringing down the others.
Atton:He was realy funny all the way,it's just sad he hadn't much to say after he's a jedi(I couldn't stand the "wanna play pazzak?"lines!!!! )
Visas:Very emotional character,I kinda like her.
HK-47:Seriously,who couldn't love HK?He's the funniest character ever!Too funny the way he's always up to butchered everyone! :D
Bao-Dur:Kinda cool too,but less great than the others.
Mira:She's great because she as a lot of attitude.
Mandalore:Same reason as HK(I just love their violent behavior)
Now the ones I didn't like...
Disciple:That guy was realy annoying.Too stupid to catch a joke,always calm,no personality,and everyone must have notice how he's a freak!!if only ther were a way to kill him!!!!Everytime he was speaking I just want to stab him with my lightsaber!Even the most kinder Jedi would wish that when speaking to him!!!
GO-TO:It' just the way he speak,I hated that.
Handmaiden:A little bit like Disciple,but she had personality at least.It's not that I really hate her,it's just that i don't like how she was always getting upset for nothing,and I didn't like her hair also(it was ugly ).
Vrook:Ok,he may be a good Jedi and all,but I hate the fact that he's always mad at you.Even if you're the most kinder guy in the galaxy,he finds a way to make you pass for an imbecile.
Atris:She's a shutta,and there's nothing more to say on her. "
And for the others,I don't really cared about them.
