Alien4...in space, no one can here you suck!
Good point about space shouldn't be able to "suck" a monster though a pinhole. That never occurred to me while watching it. At the most, maybe a nasty raspberry?
The part I didn't like about that scene is the flicking of acid onto the window. People think acid will just dissolve anything, but it really doesn't work like that. Acid is just a very good solvent for metals, and perhaps organic flesh. However, glass should be pretty darn stable. In fact, acid is stored in glass containers all the time (in a lab, for instance). I just rolled my eyes at the premise that acid could in anyway make a pinhole in a glass window.
That whole Sigorney Weaver thing and artistic input...I think we can see how easily nutty personal views can really deep six a film. It's ok to have all the personal views you want, but don't inject them into movie projects just for the hell of it. We don't go see movies because we want to see how "Sigorney Weaver" would battle xenomorphs. We go see movies to see how space people deal with xenomorphs, and if that requires lots of gunfire, that's the way it's got to be, imo.
For the longest time, she wanted a "make love to the Alien" theme, too, I hear. Get too close to some of these celebs, and you find what real kooks they are, I guess. She suggested it in Aliens production, but not until Alien4, did she get her wish. 'kay, whatever, Sig. I guess when it comes down to it, it's not like Alien4 could really have been ruined any worse Alien-luv or not.
As for the topic title...I don't know about it being the worst ever movie, but it certainly was bad. Battlefield Earth still gets my vote for worst sci-fi movie ever.
