sure, of course, the story is important
what i am getting at, is that there is another "mini-wave" of sci-fi and sci fi like films and tv shows going on now. studios are trying to cash in on it, they come up with what they can and produce it.
it just wouldn't surprise me if they tried to do so "on the cheap"=minimal alien FX and usage adds to savings when you can just use regular, un-modified actors in the 'body snatchers' modus operandi
<< i would say this mini wave,for better or worse, has been going on for a bit now. with shows like fringe, firefly, bsg,sga/sg1,etc,etc and into the current day with stuff like TWD and other non sci fi (which most viewers do not understand the genre diff anyhow) and sci fi stuff that has been coming out
it is reaching its peak now with the releases of the nuST movies and SW's films. You just know that studios without one of these "babies" in the mix are pushing hard to get their piece of the action before sci fi and sci fi-esque genre films die back again. remember all the crap sci fi movies that came out in the 70's after SW's and ST;TMP? >>
