I read all three storyarcs of the Dawn of the Jedi series today.



To quote Mr. Burns: "I know what I hate. And I don't hate this."
Right up front, I'm gonna say that I don't like the majority of John Ostrander's Star Wars work; I don't like his characters, I don't like his adoration and use of prequelisms, and I especially do not like the Legacy series -- the worst thing to ever happen to the EU since the PT.
Now, that aside, I think he did a good job with this series; there were next to no prequelisms to be found, and at least a few of the villains had a modicrum of depth to them this time around.
Of course, there were still things I disliked. I didn't like that the proto-Jedi were called "Jed'aii" -- the precursors of the Jedi should have a completely different name from their successors, not merely an alternate spelling of the same name -- and I quickly grew sick and tired of the forcesabers; it wouldn't have been so bad if the weapons had been limited to Xesh and the other Force Hound characters, but everyone from the "Jed'aii" to the Rakata soon started swinging them around and the whole scenario became an excuse to shoehorn glowing energy swords into a timeframe where they shouldn't exist.
In the end, though, I liked this series enough to accept it as deuterocanonical within my own SW Universe. That's all that really matters, right? ;-)
