I agree with propita. I'm interested in the narrative differences not as a matter of preference, but because the two "worlds" keep intersecting: so the plot of the show veers away from the books, but then a couple of characters get conflated (Herschel/Dale) or plots seem to reflect late stories from the books (does anyone else think Woodbury is starting to look more like Alexandria every day?). It's not quite Reed Richards arguing that any moment creates a new time-river; it is more like twin branches of the same river that keep coming together again.
I like the some of the changes in certain character's fates--rather, how certain negative events were shifted to supporting or minor characters, instead of what occured in the comics. TWD's producers want drama and shock, but after a time, it becomes a gimmick and sadistic--even in a horror series, when the leads are constantly abused/violated just to show how "gritty" the show can be.
