It's a good series. I put it with Gundam, Metal Gear Solid, Xenogears, and other giant complex world building mythos that I generally enjoy because they cater to my taste of war, backstabbing and epic-sized tales of grey areas and people involved in things much bigger than them.
I don't try to convince people any of them are college-level classics though. I also don't care if people don't like them, I get my kicks enjoying them and discussing them and universes with other people who enjoy them too. Stuff doesn't have to be considered objectively good for anyone to enjoy it. Tastes are pretty subjective, especially on the internet.
It's also the first book series I've ever read though, everything I've always read has been a standalone novel, novella, or short story collection; so it makes me want to try more. Thinking about reading Harry Potter next? Would read the Dark Tower series since I love 99% of everything Stephen King, but I heard the series goes to shit halfway and is incredibly disappointing in the end which makes me want to avoid starting it.
*edit* actually I did read the Dune series and one of the Star Wars trilogies back when I was a kid.
