Personally, I just (April 2015) discovered this whole collectible community in general, and predators specifically.
That said, I'm in my early 30's and discovered/watched the first film when I was 7. It was way to early, in retrospect; couldn't sleep normally for quite some time. That fear turned into fascination, then love, during my teens.
So, now, having discovered these figures, I'm totally fine with collecting toys again after a two decade hiatus.
Regarding the film's, I've seen Predator over 40 times (once in cinema), and P2 around 15. Predators ~10. AvP maybe 6 times. AvP:R is a joke, so twice.
How about you?
Regarding the new generation, I'm doing my utmost to have my mid-teen brother to watch them, or at least P1 & P2. So far, no success. But I will NEVER give up. Unfortunately, I doubt too many of the new gen peeps know about predator. Therefore I applaud the gaming industry for providinf necessary Predator-CPR every couple of years.
