Review of Dead & Buried

... much like the zombified citizens of the town, it falls apart the longer it goes on. If these undead "have no memory except what (Dr Dobbs) gives them", why on earth did he give Sheriff Gillis any inclination to investigate suspicious disappearances and deaths in the town? Because that is what totally tripped up and sent the Doctor's little project here spiraling down the toilet.

I guess the filmakers just had to push for the shock of that final twist and didn't want people to think too hard about it. But it ruins an precarious premise.
