The first Channel Zero serial, Candle Cove, is currently running on the UK's Channel 5. No jokes about that, now. It's available free on demand via the My5 site, here. Having watched the first two episodes, I find it pretty good so far.
1. It's a lot darker than I thought. Child murder is never exactly a jolly subject, but this is small town America at its most peculiar and disturbing.
2. Impressive casting and production values - not lavish, but technically well up to par.
3. No idea how much of the craziness is in the protagonist's head. It's an old trick, yes, but we are given plenty of hints that something other than a mental breakdown is going on, here.
