The first Matrix movie explained in 3 lines of dialogue :
Morpheus: Dig this -- the world is a massive illusion, created by machines to keep humans docile. You're actually a body floating in a jar.
Neo: That would explain a lot.
Morpheus: Cool. Now let's go kick some robot ass.
From some guy who thinks the movie and its sequel is way overrated.
And from that guy again , How to make a cat kill itself
Heh another really cool intepretation of Reloaded
