Okay, we all know that the people who make movies often don't know, or don't care, about how things actually work in the wonderful world of firearms, even when said firearms are an intergral part of the plot (if I see ONE more movie where bullets are bouncing off the sheet metal/fiberglass of an ordinary car, making those pretty sparks . . . ). However . . . how come when theres some large, dangerous critter running around eating the two teenagers making out in the car parked by the lake and generally causing havoc, and you call in the team of specialists, experts in guns and knives and who used to give Rambo wedgies, they go after this large armor-plated creature (like a giant croc) or seven story tall T-Rex with puny pop guns like MP5's or even M-16's. These puny rounds just bounce of Mr. Monster, and have about the same result as shooting a bear in the *** with a bb gun. Will somebody just get a REAL gun and KILL the thing already? I mean, look at the first TREMORS movie - when it broke into Reba's underground rec room, what stopped it -- the AR's, the .357's, the 9mm's ? Heck no. Burt put an end to that sucker with a double rifle in 600 nitro express (or close to it). When I go into the jungle after a rogue 'saur or giant flying reptiles, I don't want Dolph Lungren backing me up with M-16's in both hands. I'll take some skinny guy with a Barret .50 caliber. And a third guy, whose main qualification is that he runs considerably slower than I do.
