Just watched a clip of The Following
...errgh, not quite as cool as I'd hoped. Maybe Cult
will tackle this premise better, and it does look like the premises are almost entirely the same...serial killer on the loose who is using the internet (oh that dastardly internet!) to induce others to become serial killers, too.
The key here is, I want there to be a good reason these people are imitating the serial killer, and not just because they are dopes with no life. I can't stand stories that use stupidity as a motivator for characters. I'd much rather there be some zany sci fi explanation, the guy is a Goa'uld and he's controlling everyone's minds!!!
