You have to consider that this is an entire war that occurs in 19 books. It has all the members of the last war on one side against an entire new galaxy. A serious enemy that makes it all the way to the core of the original galaxy. Telling that in 19 books is very fast paced. The last one was told in about 3 movies, 40 books, tons of comics, and lots else that I cant think of right now.
I would say that the first books in the series are not quite as good as the series together. The problem is, the different technology makes it so that it just goes back and forth, and whoever has figured out some little trick is gonna win. Once you hit Star by Star (one of the best books ever IMO), the series really picks up, and is basically really good from there on out.
