Well, i agree and to some extent disagree with that statement. Yes in the interest of creativity a film director/producer has a right to ignore what has gone before, but then where does that leave the fan base that gave money to the original and should want to see the sequel and fork out their hard earned dollars/pounds. Upset the fan base and the movie will sink like a lead fart, case in point - Alien 3.

Very true, but we get thwarted by a cold. Prick us do we not bleed, well, yes but it doesn't eat through the person who pricked us, was that unnecessary complexity?

, when you look at all four films, the only one to really use that acid blood to any effect was number 4, when the aliens killed one of their own to escape a cell.

Hardly abstract, the character was a qualified science office, the operative word being SCIENCE officer.

Now I know it couldn't be absolute, but there was no evidence at the time in the film to dispute the "perfect" analogy.

I'm not sure where you're going with that, I meant that anything alien is quite refreshing in films, but not necessarily good. If it did sprout flowers from said butt, I would no longer be a fan of the series, but it would definitely raise the question.. "How crazy was that flower/butt scene?"
