That sounds compelling. Hopefully BBC America will air it, I'll have to check.
I remember a series from the UK about reality show contestants on a show like Big Brother when the zombie apocalypse strikes. Can't remember the name but I enjoyed it and was surprised by the unhappy ending IIRC. This was a around the time when The Walking Dead series started.
Can't remember the name but it was a Charlie Brooker one. If you liked it then I'd recommend his Black Mirror mini-series (about to come back for a second season).
His guardian articles are always good reading as well.
