3. 'Terminator 2: Judgment Day' (1991)
>The movie where Arnuld showed us how to properly rack a shotgun, "T2" changed the way we make blockbusters.
From its then-landmark use of CG on the T-1000, to its "bigger is better" production values that don't skimp on character (but pile on a little too much of the sappy), Cameron's last Terminator film as director influenced everything from "Jurassic Park" to, well, pretty much any movie to feature a digital character. So many of your favorite movies owe their existence to "T2," one of the best sequels ever made -- 25 years after its release.
