The marines got wiped out because they over-estimated their abilities.
They were convinced the mission would be a cakewalk. And, while they killed countless aliens in the process⌠they still backed themselves into a corner simply because they didnât take Ripley seriously when she tried to tell them what they were up against.
Using the âalienâ in the second film, had the marines actually been aware of the danger they were facing⌠they wouldâve fared better.
Hell, the stand off in the second half of the film goes better then the initial encounter. With less marines. And thatâs only because they didnât run in thinking they were untouchable.
But even so, it makes the creature only deadly in large groups. Where as the reason the alien worked so well in the first film was because it was an unknown. You donât get a good look at it, you donât know what you can do against it⌠you donât know what itâs goals are.
Something about âOh, just shoot it with a gun⌠that kills itâ takes away from the fear of the alien.
I like the second film, a lot (the original cut⌠not the directorâs cut), but the first film is the best in my eyes. The unknown, the stealth and deadliness of the alien.
Also, Iâm strongly with H.R. Gigerâs opinion⌠Iâm not big on the âredesignâ of the alien in the second film. The original design is the best.
