Aliens - 1986 movie (was Dog Soldiers)

[raketenjagdpanzer]

I love me some Aliens but it's got plot-holes big enough to drive a Conestoga class cruiser through.

1 - why in the hell did they all bunch up in the atmo. processor? Why did they not go by bounding advance for crying out loud? Hicks sees the acid damage and says straight up "looks like they bagged one of Ripley's bad guys in here". They KNOW what they're in for!

2 - The Colonial Marines Technical Manual tells us the aforementioned Conestoga class can carry "up to 90 passengers and crew, with as many as 2000 more [hypersleep chambers] in the cargo bays". Aaaand twelve marines and one APC went? WTF? That's like sending an Arleigh Burke class missile frigate out with a bridge crew and four marines. I just can't see how/why that would be done.

3 - the never-ending question of how/why the facehugger eggs got on in the first place, which triggered 3. The eggs are only activated by the presence of someone leaning close to them. The queen tore loose from the ovipositor, and even if she'd "laid" them in the landing strut well of the dropship, how'd the facehuggers hatch and find Ripley.

4 - Really, guys? EVERYBODY leaves the ship? When Burke has absolutely established that the critters are on the ground? Irrespective of his actual motives, he tells Ripley when she says "We're going to wipe them out, not bring back, not study, right?" "That's the plan." - she briefed Gorman on the danger of these things, Burke (acting as the good friend) obviously backed her - but everybody came down. WTF???

I love Aliens, don't get me wrong, but there's a lot of practical problems with the movie.
