Wandering the back corridors of YouTube, I ran across this fan video tribute to the Colonial Marines.
It's been years since I've watched Aliens, probably at least since '03 or '04, and I don't remember the gun handling and tactics stuff being that bad. I mean, yeah, I remember that there was a lot of shooting from the hip, but seriously, seeing the footage again last night of the marines unassing the APC and moving up to the doorway of the complex had me laughing out loud with all the skipping and pirouetting up to the abandoned complex, muzzles pointing every which way, and then just standing in the middle of the doorway when it opened, (the area known as the "fatal funnel") pointing their weapons menacingly from the hip like a Tropic Thunder movie poster.
In the intervening years, it's become the norm for movies to retain consultants to try and add verisimilitude, to the point that the only place you see the old traditions of Hollywood gun-handling are in comedies deliberately parodying the skipping-and-pirouetting-and-standing-in-the-open-spraying-from-the-hip traditions of Hollywood Tactical Movement, and seeing it in Aliens felt awkward for me. The movie has such a place in my memory that suddenly seeing the string holding up the rocket or the zipper on the back of the Godzilla suit was both funny and kinda sad at the the same time.
In fact, I'd wager that, given the way Hollywood influences the evolution of pop culture, Hollywood Tactical Movement may soon be gone from our cultural DNA. Hand some random 21-year-old waiting-tables-until-his-big-break actor an airsoft M16 and tell him "Act like some special operations dude going down a hallway and through a door," and he'll do it differently if he's grown up watching Black Hawk Down and 24 than if he'd grown up watching Rambo and The A-Team.
