I finished the first one (took me a LOOOONG time to get into it) and a bit into the second one.
I really only like the Glotka character.
That was my main problem. I didn't particularly like any of the characters. I agree Glotka was the most interesting, with Logen a close 2nd. But none were ones I really cared for. And the enemies weren't fleshed out at all.
Took me awhile to get into it too. I read the first few chapters of the first book and then probably didn't pick it up again for 3-4 weeks just because it hadn't grabbed my interest. The only reason I kept going was because I'd heard good things about it.
