Kind of sad I missed out on this epic thread while the show was on even though there is a huge amount of nittery ITT. I agree the show has a lot of forced drama, like Lori being an idiot and flipping her car, magical materializing Carl, but most of the inconsistencies are pretty minimal and don't really take away from the enjoyment of the show. Stuff like them not syphining gas, the writers can't possibly imagine every possible plan every audience member would do and explain in detail why they are not doing it. There is a very brief amount of time that a show/movie has to deal with the telling of a story and I think it's important to just suspend your disbelief a little. Like if every inconsistency was fixed does the show get significantly better? If you say no then maybe you just aren't into zombie movies. Every great show has consistency problems, bad acting, Poorly motivated characters but when you like the overall concept you tend to let things slide.
Other than some questionable Lori stuff and magical Carl there is very little from the first two seasons that I hated. This isn't like the wire where they are depicting team of highly trained officers who know how to implement a complex plan. These are average people, and average people tend to do dumb things. I don't think it really takes away from the believability of the show. And the show has a ton of great scenes that do not seem to get discussed ITT.
If you don't like zombie movies/tv that's fine but the creators have done a great job with their source material and this is evidenced by the fact that there isn't really any other zombie drama that can compare to TWD.
