i love how defenders of this movie hold up Aliens as the be all end all example of how aliens should be.
forget about, you know, the other 3 movies where they intelligent, strong, and deadly. forget about how 12 aliens took over a military vessel full of soliders. forget about how they were never cannon fodder in Alien, Alien3, or A:R. hell even in avp they were never this pathetic.
Aliens is the exception not the rule on how aliens are portrayed.
