The show lost me midway through Season 6 with the BS "Glen died!" thing that I totally knew they'd undo later (thanks to the magic dumpster). It was just stupid and blatantly manipulative. On top of that, I was already growing fed up with the writing overall, and how much they'd drag out plotlines. Stuff like the Wolves and Terminus would take up entire half seasons, but really only were about 1-2 issues in the comic. Traveling between places felt like it took longer than the Lord of the Rings extended versions. The show would kill characters in ways meant to be "shocking" or whatever, but it mostly just felt lame when it happened (e.g. "Everybody Ate Chris," and Beth dying).
That said, even the comic got old for me. I got the 3rd compendium last year, and it really, really felt like it had shifted away from storytelling to putting big splash pages and huge panels on pages to help save the amount of writing and storyboarding they'd have to do. It's amazing how fast a comic goes when you have a single image take up an entire page or two. So much less dialogue is necessary! The comic prior to this was never slow. It moved along at a decent clip, I felt. But it also felt like it actually explored stuff in more detail. By Compendium 3 that changed, and now I think I'm just pretty much done with the entire franchise, except maybe for eventually playing the Telltale games that I bought ages ago.
