So what does Liv Tyler, Anne Rice, & Angelina Jolie have to with SCIENCE FICTION??!!  Has Sci-Fi become a catchall for genre??!  Because when I was a kid it was SCIENCE FICTION!  Lord of the Rings was/IS Great, but what the hell does that have to do with SCI-FI.  Like the top 10 influential African Americans of sci-fi, somebody needs to learn what Sci-Fi is!

I think you're comparing apples to oranges here.  If you're going to do a list of female actors in sci-fi, do that.  If you're going to do a list of female creators in sci-fi, do that.  I think it's really hard to justify comparing the two together.

And can I just say (being a former bookstore employee) that sci-fi and fantasy are NOT the same thing.  There is a very clear line here.  If you can't see it, then you're blind.  LOTR?  Fantasy.  Aliens?  Sci-fi.  I'm a fan of both, but it's very frustrating when the two are smashed together.
 

And while I am ranting --As far as the thrown about term Genre goes, isn't that just a type of literature/entertainment ---Romance is a genre, Sci-Fi, Fantasy.  Doesn't it just mean -kind. 

I am sorruy but this list is a FAIL as Sigourney Weaver should be number 1 and Liv Tyler should be removed from the list.  This list is mostly just a list of who is hottest and that does not matter in Sci-Fi.  Weaver is smarter and most awesome in all of her best Sci-Fi roles.  Alien, Aiens, and Avatar.  END OF STORY.

Props for putting Mary Shelly on though.  She was high on wine and opium when she wrote ol Frankenstein whilst living with Lord Byron.  What a party that must have been!

Another vote for moving Sigourny Weaver higher and booting Liv Tyler off the list completely.  Winona Rider has been in more genre stuff than Tyler and could take her spot on the list, but Weaver probably should be number one.

Didn't Kathryn Bigelow also direct Near Dark?  That's an awesome movie that is very underrated.

I think the writer of this article needs to go look up what the word "influential" means.  Because the only influence Liv Tyler or Angelina Jolie have are on my boner. 

Why is Mary Shelly last on the list?  In another 50 years or so I think she and Weaver (and probably Linda Hamilton) are going to be the most remembered from this list.

This is list is also not a Sci-Fi list, it is a genre list.  Most of the people on it are not really know for real Sci-Fi movies.  That is another reason is is a fail.

What a horrible list.  I want to heave.

Angelina Jolie is most influential women of sci-fi?  Give us a break.  None of her films are sci-fi classics.  None of her roles broke any ground.   She has not impacted the genre in any neaningful way.  She's No. 1 on this list purely because of sex appeal.  Way lame.

ALIEN and ALIENS are classics of the genre.  GHOSTBUSTERS and GALAXYQUEST are also great films.  Before ALIEN (1979), women existed in sci-fi films to be rescued.  They were all damsels in distress.  Sigourney Weaver changed that.  Ripley from ALIEN is the first woman on the big screen to kill the antagonist by herself and survive without a man's help.  Weaver shattered a glass barrier with this role.

That makes Sigourney Weaver No. 1.  The fact that you missed this and ranked at her No. 7 shows how clueless you are.
