You know, I never watched Stargate until about the fifth or sixth year when I got married and my husband, who is a military-aholic watched it constantly. I bitched and complained for the first year because the show was "too military" for me and I couldn't get my sister to watch it either. She's a total Farscape fanatic who has collected all kinds of memorabilia from Farscape and from the actors. Plus I was totally disappointed with the movie - all those special effects and great background archaeological story (I was an archaeology major) just to end up on a planet with an earth colony. Where were the aliens, the exotic landscapes and languages, the strange cultures?
But after I was forcefed Stargate, I really began to love the show. The characters were great and the relationships were intriguing. I became a total fan of the show and really was enraged when it was cancelled just because Richard Dean Anderson got bored with it...gaaah...I'm so bitter over that!!
But I love the other series you mentioned. I think I may have mentioned that hubby and I met as Klingons in a Star Trek costuming group and now we're into Star Wars costuming - we're TIE pilots, officers and are constantly working on additional costumes.
As far as Matrix...I loved it until the ending of the third movie. I think the Wachowski brothers really lost their way by the time they finished envisioning the story arc.
