It seems as if everyone and anyone these days looks back at the 80s as their favourite decade, even if they weren't born in it, in part because of the wave of nostalgia seen in pop culture in recent memory. And even though I admire music from that period, I'll be quick to say upon my recent reflection of it, that even though most jams have a feel good element to them (think anything by A-ha or Duran, Duran and the such). There is very little in terms of conversation going on there. And by this I mean the umbilical cord between the listener and the performer and the world around them.
I'll just go out and say that I find the 70s to be not only the greatest decades for cinema, but also quite frankly the best decade for horror films, period. Whenever I talk to fellow cinema lovers, they'll generally agree, that is of course if they indulge in that decade as often as I do.
