From what I've read it may have been similar but I think that's what a lot of people want something that doesn't deviate too much so it doesn't feel like Star Wars.
No no, it didn't deviate ANY. It is, quite literally, just the EXACT SAME STORY. Hero of war falls to dark side, sith create new government from old, rebels etc etc etc. blah blah blah. How anyone can read it and think it's anything other than sheer garbage is beyond me. I could write it in 10 minutes. Just load the original books, and do a search and replace for the names Anakin Skywalker/Darth Vader to Jacin Solo/Darth Caedus, Old Republic to Galacitc Alliance, etc. Like no originality AT ALL. None. Total, complete lack of anything in any way resembling originality. They didn't even get rid of all the same old plot bunnies that strike at the same times. It's horrible.
I can't say I've read a comic series yet that I found to be worth the money. Most of them are poor writing at best, with plot bunnies abounding, and often HUGE plot holes that they simply ignore and cover with bunnies. Much like a lot of the lower quality EU novels, only with pictures.
