What I loved in the SW story is how it made nearly everything "by the book", in classical sith fashion, and pulled it off with flying colors. (Corruption of a young jedi, lording over slaves(vette) and other inferiors, revenge, killing your master, showing off your strength, even facing your other self - etc)
For me it was less about what happened rather than it happening according to all the laws of Sithhood. That said, Baras was absolutely great. I applaud the voice actor.
In my opinion, it's even better when you go light side, because of how well your character subverts sith fashion while the story and everything around him goes 'by the book'. You basically just go in and subvert every sith trope. . . and many jedi ones.
