So, er... about me finishing off Buffy and Angel before I start anything else? I'm on it, really I am, but we have a missing disc from Angel season four that I suspect to be 200 miles away and... Mrs Llamastrangler and I just happened to start watching The Walking Dead. So I might as well blog it.
Yes, this origin story, with Rick waking from a coma to find that the zombie apocalypse has happened, is more than a little Day of the Triffids, but it's also a neat short cut; we all know the zombie tropes, which also helps. It's an extra-long opening episode, but a lot of its work has already been done with the tropes being familiar. Including the cop show stuff at the start, which was pure Dukes of Hazzard.
