Dunno [kinda OFF TOPIC] I really don't see the point in complaining about a "trend" (or wathever this may be), just enjoy the things you like that come out of it, and don't give a shit about the useless ones.
Luckily series/films etc are (usually) not copycats of each other, coz of different "targets" etc.
example: covers of a "popular" magazine
twilight
true blood
I think they are "perceived" in different ways, not "it's all the same vampires stuff".
There are GOD KNOWS how many tv series/movies with cops and criminals.
I watch the ones I like or find interesting and I don't watch the ones I don't consider interesting/likable, but I don't hear much people complaining about "all this people-with-guns shit".
This is not a post "against" pbradly (also because I'm not 100% sure about the meaning of his post), just a generic opinion. Lots of people say "enough with fangs, jeez", like there's nothing else going on beside vampires stuff..mboh!
