I just finished American Gods. I honestly didn't enjoy it much. It took me 3 weeks to finish because I'd pick it up, read a chapter or two, and get bored. I hated that I had to wonder for 400 pages what was happening. There was too much ambiguity, and too much bouncing around. I never connected with ANY of the characters except Shadow, and even he was hard to connect with because he just kinda shrugs his way through all this ridiculous stuff happening.
3.5 / 5 from me. I can tell I'd probably nudge that score up to a 3.8/5 or something if I read it again, since I know what happens now, and I'd pick up on some more subtlety.
