From the first two seasons, which is all I've watched, she seems like just as much of a loose canon as Shane (and deserves the same fate, in my opinion). I got up through the penultimate episode of season 2 and then decided to stop watching. I wouldn't say it's a bad show, but after they killed off Dale I just didn't see any reason to keep watching. He was pretty much the only character who strived to maintain civilized morals, and as such was the only character who I didn't find completely obnoxious (well, okay, him and Daryl). With him went all my interest in the show. Hershall is actually similar to Dale now. He's not how he was in Season 2.
